In this problem you will count the exact number of steps for the code segment below. You should count each assignment and each comparison as one step. i = n; sum = 0; while (i > 0) { // this is the body of the loop j=i* 2; } sum sum + k=i*j; + j; i=i-1; Q1.(1 points) How many steps are executed when n is 0? Q2.(1 points) How many steps are executed when n is 1? Q3.(2 points) How many times does the body of the loop execute? Q4. (6 points) The total number of steps in an execution of the code segment is 9
