i need the answer quickly
a)(i). People often use recursive algorithms. Discuss the difference between direct recursion and indirect recursion. In which situations would a direct or indirect recursion be a better choice to use?(ii). Two Level 200 IT students, James and Morris, are discussing how to compare two algorithms for solving a given problem. James suggests that they should use the execution times of the algorithms as criterion; but Morris insists that they should use the number of statements the algorithms execute as criterion. (α)Explain the reasons why both criteria they are considering are not good for comparing algorithms. (β)Recommend an ideal solution/criterion that they should rather use for comparing algorithms. Give a practical example to illustrate your answer.

Question below 11. USE PYTHON LANGUAGE. READ INPUT FROM FILE (NAME THE FILE "input.txt') The problem needs to be solved using Greedy Algorithm Strategy. Jack and Jill’s parents decide to make their children do some house chores. So they list a set of activities that can be completed in a whole day. In order to complete each activity a certain amount of time (in hours) is required. The parents randomly call each of their children several times separately to choose from the given activities. In each call the children choose an activity based on the following conditions: In each call, each of them chooses one activity Jack has to choose an activity that has not been selected yet. Jill, being very little, should choose an activity that Jack has already chosen so that she can help her older brother because she cannot do such tasks by herself. Jack does not like doing chores, so he decides he would choose the activity that requires the shortest amount of time to complete among the…
