- Suppose that there are N events to be held this year. The ith event is scheduled from day si to day ti, and free food is to be served for that event every day from day si to ti (inclusive). Your task is to find out how many days there are in which free food is served by at least one event. For example, let N = 3 events. The first event is held from day 10 to 14, the second event is held from day 13 to 17, and the third event is held from day 25 to 26. The days in which free food is served by at least one event are 10, 11, 12, 13, 14, 15, 16, 17, 25, 26, for a total of 10 days. Note that both events serve free food on days 13 and 14, and therefore they are only counted once. The first line the user will supply you is an integer, N, denoting the number of events. Each of the next N lines contains two integers si and ti denoting that the ith event will be held from si to ti (inclusive), and free food is served for all of those days. The output contains a single integer which denotes the…For all positive numbers aaand bbwith a>ba>b, ln(a−b)=ln(a)/ln(b)ln(a−b)=ln(a)/ln(b) True or falseA group of individuals are living on an island when a visitor arrives with an unusual order: all blue-eyed people must leave the island immediately. Every evening at 8:00 p.m., a flight will depart. Everyone can see everyone else's eye colour, but no one knows their own (nor is anyone allowed to tell them). Furthermore, they have no idea how many people have blue eyes, but they do know that at least one person has. How long will it take for the blue-eyed individuals to leave?

For example, Bowler (B-2) bowled 3 overs, 5 dot-balls, 3 wickets taken, and 14 runs conceded. Stats for other bowlers are represented by the other rows in a similar fashion. Write a MATLAB® script to compute a) The economy rate for each bowler. (hint: In cricket, a bowler's economy rate is total number of runs they have conceded per over bowled.) b) Which bowler has the lowest bowling average. (a player's bowling average is the number of runs they have conceded per wicket taken. hint: min command with index value will be helpful here). c) The total number of dot balls bowled by all five bowlers.

During development, three different algorithms were created. • Algorithm A runs in constant time, with a maximum runtime of 1.10 seconds and returns all matching results. ● Algorithm B runs in logarithmic time, with a maximum runtime of 0.3 seconds, and returns only the first result. ● Algorithm C runs in linear time, with a maximum runtime of 1.50 seconds and returns all matching results. Which algorithm would be the least suitable for the requirements stated? In your answer, justify your choice by explaining why you picked that algorithm, and why you did not pick the other two algorithms.OND OND OND DAD
