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 … WebSep 26, 2011 · If it is performed n times then it will take n units of time. Outer loop executes inner loop n times. So in essence i==j operations is done n^2 times. All nested loops mean O(n^(no of nested loops)). Here O means the upper limit which means code will execute in less than or equal to the value of O().
