unordered_set:

class Solution {

public: vector<string> findWords(vector<string>& words) { vector<string> res; unordered_set<char> row1{'q','w','e','r','t','y','u','i','o','p'}; unordered_set<char> row2{'a','s','d','f','g','h','j','k','l'}; unordered_set<char> row3{'z','x','c','v','b','n','m'}; for (string word : words) { int one = 0, two = 0, three = 0; for (char c : word) { if (c < 'a') c += 32; if (row1.count(c)) one = 1; if (row2.count(c)) two = 1; if (row3.count(c)) three = 1; if (one + two + three > 1) break; } if (one + two + three == 1) res.push_back(word); } return res; }
