Plus Minus
Given an array of integers, calculate the ratios of its elements that are positive, negative, and zero. Print the decimal value of each fraction on a new line with 6 places after the decimal. Note: This challenge introduces precision problems. The test cases are scaled to six decimal places, though answers with absolute error of up to 10^ -4 are acceptable. Example : arr = [1,1,0, -1,-1] There are n =5 elements, two positive, two negative and one zero. Their ratios are 2/5=0.400000 , 2

Given a time in 12 -hour AM/PM format, convert it to military (24-hour) time. Note: - 12:00:00AM on a 12-hour clock is 00:00:00 on a 24-hour clock. - 12:00:00PM on a 12-hour clock is 12:00:00 on a 24-hour clock. Example s = '12 : 01: 00PM' Return '12:01:00'. s = '12 : 01: 00AM' Return '00:01:00'. Function Description Complete the timeConversion function in the editor below. It should return a new string representing the input time in 24 hour format. timeConversion h
