how to reverse a number?
Example1: x = 123, return 321 Example2: x = -123, return -321
this is my answer:
public int reverse(int x) {
int result = 0;
while(x != 0){
result = result * 10 + x % 10;
x = x / 10;
}
return result;
}
but when I input 1534236469 , it will output 1056389759 , this is wrong. what do you think about my program? thanks.
