Explanation

There are 5 integers to multiply. Let's store the final answer in answer variable. Since 1 is identity value for multiplication, initialize answer as 1.

So the process goes as follows:

answer=1
answer=(answer×1) % (109+7)
answer=(answer×2) % (109+7)
answer=(answer×3) % (109+7)
answer=(answer×4) % (109+7)
answer=(answer×5) % (109+7)

The above process will yield answer as 120
