Searching for the number of substrings in a given text that start with the letter A and end with the letter B. For example, in the DABAAKBSA text, there are 4 substrings that begin with the letter A and end with the letter B. a) Design a brute-force algorithm that performs the desired operation above and implement it in c language. Let the searched text be entered by the user.

b) Calculate the time complexity of the algorithm you designed.

c) Design an algorithm that is more efficient than the brute-force algorithm and implement it in c language. Let the searched text be entered by the user.

d) Calculate the time complexity of the algorithm you designed and compare it with the brute-force algorithm.

Write a grading program for a class with the following grading policies: a. there are two quizzes, each graded on the basis of 10 points. b. there is one midterm exam and one final exam, each graded on the basis of 100 points. c. the final exam counts for 50% of the grade, the midterm counts for 25%, and the two quizzes together count for a total of 25%. (do not forget to normalize the quiz scores. they should be converted to a percentage before they are averaged in.) any grade of 90 or more is an a, any grade of 80 or more (but less than 90) is a b, any grade of 70 or more (but less than 80) is a c, any grade of 60 or more (but less than 70) is a d, and any grade below 60 is an f. the program will read in the student’s scores and output the student’s record, which consists of two quiz and two exam scores as well as the student’s average numeric score for the entire course and final letter grade. define and use a structure for the student reco
