Task 1: Calculation of the time complexity of different algorithms What is the run time complexity of the following algorithms? Explain in your words how you got the solution. 1) int a = 0, b = 0; for (i = 0; i 0) { } a += 1; 1 / = 2; 4) int a 0, i = N; for (int m= 0; m < 5; m++) { while (i > 0) { a += i; i / = 2;
