[bablurani]

In POW(X, N) question, the reason to convert "n" into Long is in given scenario "n" is int so if we directly multiply it with -ve so its positive value exceeds the boundary of positive integer data type. So to increase the boundary we convert the data into higher limit data type.

Awesome thought. Together, our knowledge can help so many students.
