Write a function that takes a string as input and returns the string reversed.
Example:
Given s = "hello", return "olleh".
1 char* reverseString(char* s) { 2 int i; 3 int j; 4 char temp; 5 i = 0; 6 j = strlen(s) - 1; 7 while(i < j){ 8 temp = s[i]; 9 s[i] = s[j]; 10 s[j] = temp; 11 i++; 12 j--; 13 } 14 return s; 15 }
