Look at given constraints, 1<=t<=100 Think of what can you do to store such a large number, Fact of 100 is 9.332622e+157 that much large.

The factorial of the values in the constraints, 1<=t<=100 soon exceeds even long datatype in java,and you are using int (int fact = 1). It has a pretty convenient solution in java using BigInteger datatype. You can read about it here
