Using another example onS = "abcd", if we have both the replacement operationi = 0, x = "ab", y = "eee", as well as another replacement operationi = 2, x = "ec", y = "ffff", this second operation does nothing because in the original stringS[2] = 'c', which doesn't match...
LeetCode in C++ 833. Find And Replace in String To some string S, we will perform some replacement operations that replace groups of letters with new ones (not necessarily the same size). Each replacement operation has 3 parameters: a starting index i, a source word x and a target word ...
