help with complexity analysis for loop:

Problem: Please analyze the time complexity of the following functions or for- loops. For each question, use the following template to figure out the total time needed to finish the corresponding function or for-loop Line No. Time taken to run this line of code Total number of times needed to run this line. Once. Total time needed to finish this function or loop Submission: Please submit your solution as one PDF file. This PDF will contain three tables in the above format, corresponding to your complexity analysis to the three questions. Q1. double sum skip7 (double array0, int n) lln: size of the array. Assume n is divisible by 7,i.e.,n 7 k, where k is a positive integer double sum-0 for (int i 0; ikn; i i+7) sum sum array[i]; return sum
