Here is a java code for long % int (long mod int)

long v = 51;
long result = v%(10^9 + 7);

what is result value. it may looks to be surprised that result is 25.

result is supported to be 51.

here is right way to go.

long v = 51;
long result = v%100000007L
int finalResult = (int) result;

Idea here is very clear that we convert long%int to be long%long and convert result to be int.
