Write a program that asks for a string. Then, it populates the elements of an integer array to keep track of the counts of each character in the given string. To make it simple, the string only contains alphabetical characters from a to z and from A to Z. After getting the counts, print the characters(first uppercase and then lowercase) and their counts from the array that you created in the alphabetical order, if they occur at least once in the string (in other words the value of the element of the array is higher than zero). Hint: You can create an integer array of size 26 and use the positions of the array to keep track of the respective alphabet's count. Expected output 1 (bold is user input) Enter a word: Colorado C: 1 a: 1 d: 1 l: 1 o: 3 r
