We have two strings A and B which are permutations of the same set of characters. We need to change these strings to obtain two identical strings by performing the following operations: swap two consecutive characters of a string swap the first and the last characters of a string The operation can be […]

For two strings A and B, we define the similarity of the strings to be the length of the longest prefix common to both strings. For example, the similarity of strings “abc” and “abd” is 2, while the similarity of strings “aaa” and “aaab” is 3. Calculate the sum of similarities of a string S […]
