@akash.dinkar12  : sorry: I am changing $m$ with $k$ inside the code.

ur previous code                                                current code

Output should remain same, how can replacement affect the output by only changing the name of variable....

I did not mean that: I changed $m$ because I also mentioned $n = m$ statement:: not to confuse , I changed $m$ with $k$ inside the code.
