class Solution { public: int lengthOfLongestSubstring(string s) { vector<int> bar(200, -1); int N = s.size(); int result = 0; int l = 0, r = 0; while (r < N) { if (bar[s[r]]>=l) { result = max(result, r - l); l = bar[s[r]] + 1; } bar[s[r] ] = r; r++; } result = max(result, r - l); vector<int>().swap(bar); return result; } };
