Description: the fault is not an integer. The parseint (), when the Numbers in parentheses is small, such as ss=12345 is not an error, when in parentheses is SSS parseint () of the largest number, not an error, but the ss=1999999999 (SSS) and an error, is this why? Bosses give directions

Sb. Reverse () this step is to turn, more than the maximum of type int, so abnormal conversion

No integer maximum range is two billion one hundred million, is a maximum of 1999999999, more than range

The number 9999999991 is not more than the maximum?
