代码(首刷看解析 2024年2月18日):
class Solution {
public:vector<int> partitionLabels(string s) {int hash[27] = {0};for (int i = 0; i < s.size(); ++i) {hash[s[i] - 'a'] = i;}vector<int> res;int left = 0;int right = 0;for (int i = 0; i < s.size(); ++i) {right = max(right, hash[s[i] - 'a']);if (i == right) {res.emplace_back(right - left + 1);left = i + 1;}}return res;}
};
