Leetcode: Find And Replace in String To some string S, we will perform some replacement operations that replace groups of letters withnewones (not necessarily the same size). Each replacement operation has3 parameters: a starting index i, a source word x and a target word y. The rule is ...
Each replacement operation has 3 parameters: a starting index i, a source word x and a target word y. The rule is that if x starts at position i in the original string S, then we will replace that occurrence of x with y. If not, we do nothing. For example, if we have S = “...
