- City and State. Extract the city name and state from strings like “Utica, NY” and “Los Angeles, CA”. Assume the state is always the last two characters in the string, the city name has at least one character, there is a comma following the city name, and a single space after the comma. Use the split method to separate the city name from the state (Notice the city name will still have a comma at the end). The following attachement is a sample execution:Code it. How do you find the count for the occurrence of a particular character in a string?.Determine if a string contain atleast 1 sandwich string. A sandwich string is a string with atleast 3 characters with first and last character being equal and the middle characters are all the same but not equal to the first and last characters. Print "True" if there is atleast one sandwich string, and False otherwise. Example: poooop - "True" holololaa - "True" Image - "False" Note: do not use def function in the program.
- Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1 below. Expression Effect strVar.at(index) Returns the element at the position specified by index strVar[index] Returns the element at the position specified by index strVar.append(n, ch) Appends n copies of ch to strVar, where ch is a char variable or a char constant strVar.append(str) Appends str to strVar strVar.clear() Deletes all the characters in strVar strVar.compare(str) Returns 1 if strVar > str returns 0 if strVar == str; returns −1 if strVar < str…Create a string from two given strings by concatenating common characters of the given strings. Sample Input harry, hermione dean, tom Sample Output hrrhr Nothing in common. Again, you have lost your USIS password!! You went to the registrar office and requested for a new password. This time, you need to follow some rules to set your password. Otherwise, they won't change it. The rules are At least one lowercase letter At least one uppercase letter At least one digit (0-9) At least one special character (_ , $ , #, @) Your task is to find whether a given password follows all those rules. If it breaks any rule, you have to print Lowercase Missing, Uppercase Missing, Digit Missing or Special Missing respective to the missing case. For more than one rule break, print all the rules that were broken (order doesn't matter). If the password is ok, print OK. Sample Input ohMyBR@CU ohmybracu OhMyBR@CU20 Sample Output Digit missing Uppercase character missing,…This program is a simple example of manipulating stringcontent. On Line 8, we print out the first element of the stringstr1. On Line 9, we accessed the first element of the stringstr2 and assigned the character ‘K’ to it. When Line 10 is called, the content of str2 is now updated. Line 12 shows us string concatenation. What happened on Line 14?
- Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number, and all the characters in the password are replaced by x. (The Social Security number is in the form 000- 00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element.I have to add this solution to a conversion code. This chapter is focused on strings and string manipulation, including slicing, searching, splitting, and case conversions. Can you help me with this? 1. Ask the user for their name and their email address before you display the results of the conversions. 2. When the user enters the email address search the string for the @ symbol. If the symbol is not found, ask the user to re-enter their email address till they get it right. 3. When you display the conversion output to the user, you must include the user’s name in the outputIn JAVA language, WAP to input a multi-word string and remove all whitespaces from the string. Print the string formed after removing all the whitespaces.
- Create a single regular expression that matches a string of digits and contains exactly two fives. Examples of acceptable strings include: "15445 " , " 55 " , " 05563 " . However, the string is to be rejected if it contains anything other than digits.A. Which statement about regular expressions is correct? a. To find all occurrences of a matching substring for a regular expression, you must add thegflag. b. By default, pattern matching using regular expressions locates all matches in the searched string. c. To find all occurrences of a matching substring for a regular expression, you must add theiflag. d. The default behavior of a regular expression is modified by adding flags to the beginning of the expression. B. After the following JavaScript statements execute, the value ofcrayonsis["pink", "blue", "green"]. let crayons = ["pink", "purple"];crayons.shift();crayons.unshift("blue", "green"); Select one: True FalseRevorse the vewels def reverse_vowels(text): Given a text string, create and return a new string constructed by finding all its vowels (for simplicity, in this problem vowels are the letters found in the string 'aeiouAEIOU') and reversing their order, while keeping all other characters exactly as they were in their original positions. However, to make the result look prettier, the capitalization of each moved vowel must be the same as that of the vowel that was originally in the target position. For example, reversing the vowels of 'Ilkka' should produce 'Alkki' instead of 'alkkI'. Applying this operation to random English sentences seems to occasionally give them a curious pseudo-Mediterranean vibe. Along with many possible other ways to perform this square dance, one straightforward way to reverse the vowels starts with collecting all vowels of text into a separate list, and initializing the result to an empty string. After that, iterate through all positions of the original text.…
