Write a function that prints a binary tree level-by-level.
I was given a short function in C (dictated because we were hanging on a phone): int foo(int a) { int result = 0; while (a >>= 1) result += 1 return result } And my task was to say what's wrong with this function, what's its purpose and what would I write my colleague who submitted it for a code review
