387. First Unique Character in a String

C++

class Solution {
public:
    int firstUniqChar(string s) {
        int m[26];
        for(int i=0;i<26;i++)
        {
            m[i]=0;
        }
        for(int j=0;j

Java

public class Solution {
    public int firstUniqChar(String s) {
        int m[]=new int[26];
        for(int j=0;j

Javascript

/**
 * @param {string} s
 * @return {number}
 */
var firstUniqChar = function(s) {
        var m=[];
        for(var j=0;j

最优解，一样

注意C++中int数组定义后，值随机，Java中定义后值为0
