int len = s.length();
if (pos < len && s.charAt(pos) == '-') {
    pos++;
    sign = -1;
if (base == 0) {

intatoi(String str)
atoi 
int retVal = 0;
for (int i = 0; i < str.length(); i++) {
    retVal += (str.charAt(i) - '0') * power(1, str.length() - i - 1);
return retVal;
int[]atoi(String[] s)

int[] res = new int[s.length];
try {
    for (int i = 0; i < res.length; i++) {
