Hackerrank String Reduction Solution
This is the solution to the program, solved in python. The Question can be found in the Algorithm domain of Hackerrank.
Problem Statement:
Given a string consisting of letters, a, b and c, we can perform the following operation: Take any two adjacent distinct characters and replace them with the third character. For example, if 'a' and 'c' are adjacent, they can replaced by 'b'. Find the smallest string which we can obtain by applying this operation repeatedly?
