long arrayToLong(final int[] digits)
eg: number = { 1, 2, 3, 4 }, returns a long = 1234 if the number correspondent of digits is bigger than Long.MAX_VALUE, so Long.MAX_VALUE is returned.

long result = 0;
long pot = 1;
for (int i = digits.length - 1; i >= 0; i--) {
 long partial = digits[i] * pot;
 if (Long.MAX_VALUE - result - partial > 0) {
 result += partial;
 } else {
 return Long.MAX_VALUE;
