• Given a list of n distinct integers, devise an algorithm to print the index of all pairs having the sum equals to a given input value k. This method takes a list, and an integer k as input arguments. So for example, if the pair az = 2 and ag = 3 and k = 5, then the algorithm should print(3, 6), and all other pairs with the same property. What is the running time of this algorithm? Assume for the previous problem the input list is sorted, modify the previous algorithm to run faster. What is the running time now? (No Credit will be given for O(n2) algorithms)
