给你一个字符串 s 和一个 长度相同 的整数数组 indices 。
请你重新排列字符串 s ,其中第 i 个字符需要移动到 indices[i] 指示的位置。
返回重新排列后的字符串。
输入:s = "codeleet", indices = [4,5,6,7,0,2,1,3]
输出:"leetcode"
解释:如图所示,"codeleet" 重新排列后变为 "leetcode" 。
示例 2:
输入:s = "abc", indices = [0,1,2]
输出:"abc"
解释:重新排列后,每个字符都还留在原来的位置上。
示例 3:
输入:s = "aiohn", indices = [3,1,4,2,0]
输出:"nihao"
示例 4:
输入:s = "aaiougrt", indices = [4,0,2,6,7,3,1,5]
输出:"arigatou"
示例 5:
输入:s = "art", indices = [1,0,2]
输出:"rat"
char * restoreString(char * s, int* indices, int indicesSize){

int len = indicesSize + 1;
char *pbuf = NULL;
char *ptr = NULL;
pbuf = (char *)malloc(len);
if (NULL == pbuf)

for (i=0; i<indicesSize; i++) {
ptr[indices[i]] = s[i];
}
return pbuf;
