Notes: added binary exponentiation

[jay-tux]

fixes #1734

[Panquesito7]

A question: is the same algorithm as this algorithm? If so, we might have to rename this to binary_exponentiation2.cpp.

[jay-tux]

My bad. It seems that is the case. Didn't check that directory as issue #1734 mentions it under divide and conquer. Does this mean either of the two algorithms have to move to another directory?

No, it's totally fine as-is 😄 Let us rename this file to binary_exponentiation2.cpp.

[jay-tux]

Renamed it!

Hmm, no idea why it's failing. Any ideas?

Okay, I found the issue here Okay, I found the error here https://github.com/TheAlgorithms/C-Plus-Plus/runs/4096578335?check_suite_focus=true#step:4:250 could you please fix it? Let us know if you need any help! Thanks. slightly_smiling_face

I don't thing that's the issue. It points to a warning but it actually compiles to an executable afterwards, so that couldn't be the issue.

It is more of a warning, not an error, I think. But there could be a loss of data there, so please try to investigate. 🙂
