Answer Posted / dhruv
I am not giving an answer, but just wanted to point out that
most of the solutions which try to add (a+b) and then
subtract from it will not work if (a+b) exceeds the maximum
value an int can hold.
So even if it looks good on paper it will give erroneous
results when run on a machine
