WebComplexity is related to the rate of growth of the number of operations. Unrolling your loop does not change that. So: foreach (element in myArray) { doSomeAction (element); } Has 0 (1) if the number of elements in myArray is bounded. The complexity will be decided by the number of iterations in the while loop. WebAnswer (1 of 2): Think upon you algorithm and try to do it with a single loop. If this doesn’t work, you can try decreasing number of iterations based on some conditions. Maybe we can skip a few iterations, use break. Without the code, it’s just guesses.
