given constraint -> numbers should be greater than 0 does it mean input no or the answer
like in subtraction operation ans cant be 0 or negative?
also in modular and division operation (like n1%n2) what if n2 is 0 it is not given what should we do in this case. should we reverse the no or we dont perform the operation?
