For the better understanding of time taken. (#6583)
* For the better understanding of time taken.

In this change I have initialized a variable p with the value of (1e9+7) and then took the modulus of process time with it . This modification gives better time taken by the process . Firstly it was giving answer in the exponential now it gives in the integer form.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Apply suggestions from code review
