实现源码

class Solution {public:    void replaceSpace(char *str,int length) {        char temp[999999];        int i = 0;        int j = 0;        while(i<length) {            if(str[i] != ' ') {                temp[j++] = str[i++];            }            else {                temp[j++] = '%';                temp[j++] = '2';                temp[j++] = '0';                i++;            }        }        strcpy(str,temp);    }};
