Your approach is correct.

This is the Accepted solution. I just changed some variable types to “long long int” and it was accepted.

If you have to multiply 2 numbers whose product cannot be stored in an int type variable, then the two numbers multiplied should also be “long long int”.

For example:

if you have to perform c=a*b and a=10^9 and b=10, then a,b and c all should be “long long int” type.

The answer about `c = a*b`

is not exact. Basically only `c`

have to be `long long`

, because `a`

and `b`

fits in int, but compiler have to know, that you really do not want int overflow, but `long long`

calculation. You can achieve this by casting or multiplying by `1LL`

.

Of course having all as `long long`

is the simple and safe approach.
