Correct answer will be upvoted else downvoted. Computer science.
You are given two positive (more noteworthy than nothing) integers x and y. There is a variable k at first set to 0.
You can play out the accompanying two kinds of tasks:
add 1 to k (i. e. allocate k:=k+1);
add x⋅10p to k for some non-negative p (i. e. relegate k:=k+x⋅10p for some p≥0).
Track down the base number of tasks depicted above to set the worth of k to y.
Input
The main line contains one integer t (1≤t≤2⋅104) — the number of experiments.
Each experiment comprises of one line containing two integer x and y (1≤x,y≤109).
Output
For each experiment, print one integer — the base number of tasks to set the worth of k to y.

- Correct answer will be upvoted else downvoted. Computer science. You have two positive integers an and b. You can perform two sorts of tasks: a=⌊ab⌋ (supplant a with the integer part of the division among an and b) b=b+1 (increment b by 1) Track down the base number of activities needed to make a=0. Input The primary line contains a solitary integer t (1≤t≤100) — the number of experiments. The main line of the depiction of each experiment contains two integers a, b (1≤a,b≤109). Output For each experiment, print a solitary integer: the base number of activities needed to make a=0.Correct answer will be upvoted else downvoted. Computer science. You are given an integer n. Check if n has an odd divisor, more noteworthy than one (does there exist such a number x (x>1) that n is separable by x and x is odd). For instance, assuming n=6, there is x=3. Assuming n=4, such a number doesn't exist. Input The primary line contains one integer t (1≤t≤104) — the number of experiments. Then, at that point, t experiments follow. Each experiment contains one integer n (2≤n≤1014). If it's not too much trouble, note, that the input for some experiments will not squeeze into 32-cycle integer type, so you should use no less than 64-digit integer type in your programming language. Output For each experiment, output on a different line: "Indeed" if n has an odd divisor, more noteworthy than one; "NO" in any case. You can output "YES" and "NO" regardless (for instance, the strings yEs, indeed, Yes and YES will be perceived as certain).Correct answer will be upvoted else downvoted. Computer science. You are given a positive integer x. Check whether the number x is representable as the amount of the solid shapes of two positive integers. Officially, you really want to check in case there are two integers an and b (1≤a,b) to such an extent that a3+b3=x. For instance, in the event that x=35, the numbers a=2 and b=3 are reasonable (23+33=8+27=35). In the event that x=4, no pair of numbers an and b is reasonable. Input The primary line contains one integer t (1≤t≤100) — the number of experiments. Then, at that point, t experiments follow. Each experiment contains one integer x (1≤x≤1012). Kindly note, that the input for some experiments will not squeeze into 32-cycle integer type, so you should use something like 64-bit integer type in your programming language. Output For each experiment, output on a different line: "Indeed" in case x is representable as the amount of the 3D shapes of two…
- Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get four cards from each suit and display the four cards picked (it is possible that a card may be picked twice).In mathematics, a prime number is a natural number greater than 1 that is not a product of two smaller natural numbers, i.e. is it has only two factors 1 and itself. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 x 1, involve 5 itself. Note that the prime number series is: 2, 3, 4, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, .. a. Write a Java method named isPrime that takes a natural number as a parameter and returns the if the given number is prime or not using the following header: Public static boolean isPrime (int num) b. Write a Java class called PrimeNumbers that: Reads from the user a natural value n (should be less than or equal 200). Prints a list of the prime numbers from 2 to n and their number and values. The program has to work EXACTLY as given in the following sample run. Hints: You should create a single dimension array to store the prime…In mathematics, a prime number is a natural number greater than 1 that is not a product of two smaller natural numbers, i.e. is it has only two factors 1 and itself.

- In number theory, a happy number is a number which eventually reaches 1 when replaced by the sum of the square of each digit. For instance, 13 is a happy number because 1² +3² = 10 and 1² + 0² = 1. On the other hand, 4 is not a happy number because the sequence starting with 4² 16 and 126² = 37 and eventually reaches to 4 that is the number that started the sequence, and so the process continues in an infinite cycle without ever reaching 1. Write, Compile and Execute a Java method that computes whether a given number is happy or sad.The greatest common divisor of two positive integers, A and B, is the largest number that can be evenly divided into both of them. Euclid's algorithm can be used to find the greatest common divisor (GCD) of two positive integers. You can use this algorithm in the following manner: 1. Compute the remainder of dividing the larger number by the smaller number. 2. Replace the larger number with the smaller number and the smaller number with the remainder. 3. Repeat this process until the smaller number is zero. The larger number at this point is the GCD of A and B. Write a program that lets the user enter two integers and then prints each step in the process of using the Euclidean algorithm to find their GCD. An example of the program input and output is shown below: Enter the smaller number: 5 Enter the larger number: 15 The greatest common divisor is 5You have N magical bags of candies in front of you. The ith bag has A; candies in it. It takes you one minute to finish a bag of candies, no matter how many candies are in it. Every time you finish a bag with X candies in it, the bag is magically replenished with X/2 (rounded down to the nearest integer) more candies. Write an algorithm that determines the maximum number of candies you can eat in K minutes. Also determine the time complexity of your algorithm in the worst case situation. The input is a sequence of integers. The first integer N is the number of bags. The next integer K is the number of minutes you have. The next N integers is the number of candies in the bags. The output of your program is a single integer which represents the maximum number of candies you can eat. If the input is 5 3 2 1 7 4 2. the output would be 14.
- Little Frank loves mathematics. Every day, he solves some mathematical problems to improve his skill. A few days ago, he found a popular problem about turtles. The problem is as follows. Little Frank is given R rectangles, numbered 1 through R. The width and height of the i-th rectangle are Ni and M¡ unit respectively. There is a turtle located on the top-left corner of each rectangle. For each rectangle, count the number of ways the turtle can reach the bottom-right corner, if each turtle can only move right or down 1 unit at any time. The turtle is not allowed to move outside the rectangle, but, of course, the turtle can move on the boundary of the rectangle. In less than one second, this problem was solved for all rectangles. He felt that the problem was too easy. This morning, Little Frank wanted more challenges. Thus, for each rectangle į, he cut and removed a rectangle of A¡ x Bị unit from the top-right corner. See the following figure for detail. Bị Mi He could not solve this…IN JAVA Alice and Bob are playing a board game with a deck of nine cards. For each digit between 1 to 9, there is one card with that digit on it. Alice and Bob each draw two cards after shuffling the cards, and see the digits on their own cards without revealing the digits to each other. Then Alice gives her two cards to Bob. Bob sees the digits on Alice’s cards and lays all the four cards on the table in increasing order by the digits. Cards are laid facing down. Bob tells Alice the positions of her two cards. The goal of Alice is to guess the digits on Bob’s two cards. Can Alice uniquely determine these two digits and guess them correctly? Input The input has two integers p,q (1≤p<q≤9) on the first line, giving the digits on Alice’s cards. The next line has a string containing two ‘A’s and two ‘B’s, giving the positions of Alice’s and Bob’s cards on the table. It is guaranteed that Bob correctly sorts the cards and gives the correct positions of Alice’s cards. Output If Alice can…Tiling: The precondition to the problem is that you are given threeintegers n, i, j, where i and j are in the range 1 to 2n. You have a 2n by 2n squareboard of squares.
