Write a function shufflestring( pairs, s) that swaps characters of s as specified by the indices present in the pairs variable. pairs is a 2-column matrix, where on each row, you are given the positions of the two characters you need to swap. If s is not given, use s='O0O0O0OO000OO0OO0O00OOOOO0OO00O0O00OO0OOO0OO0OO0OOOOO00O0O00000O'
