Two binary strings str1 and str2 of the same length are given and we have to maximize a given function value by choosing the substrings from the given strings of equal length. The given function is such that − fun(str1, str2) = (len(substring))/(2^xor(sub1, sub2)). Here, len(substring) is the length of ... Read More
