Question

If(result>integer.max_value/10 || result== integer.max_value/10 && A >7) return 0;
Plz , can anyone help me with this?

Answer 1

That's all doing reverse of an Integer..
If the resulted values going exceed the Integer range then it just returning 0.
result >= Integer.max_value/10 is there to check that just in next adding reminder will produce incorrect overflow result..

Answer 2

|| result== integer.max_value/10 && A >7) return 0;

Answer 3

Then what is the use of this

Answer 4

Integer Max value is 2147483647 and min value is -2147483648
So here look, last digit is 7,more than 7 and already result>=Integer.max_value/10 true then it cause overflow similar for next condition for - 8, min value.
I combined > and = to >=.
There are actually redundant checks..
