c++ program to find the longest radical string. Consider a string containing only letters of the English alphabet, which may contain upper or lowercase characters. A string is considered radical if it contains both the uppercase and lowercase equivalent of a letter. For example “XyYx” would be considered radical since it contains both an uppercase ‘x’ and a lowercase ‘x’, and same for uppercase and lowercase ‘y’. Your function longestRadical will take in a string and return the longest radical substring (assume the user is benevolent and cannot produce an output that will error your code, that is to say worry about only [A...Za...z]) find the longest occurring substring using a divide and conquer approach. If multiple strings would be tied for the longest overall substring length return the later occurring string (relative to the original inputted string).
