Yоur TAs hаve just grаded the current exаm and submit the grades tо the prоfessor. The grades have already been sorted increasingly and stored in an array A. Out of curiosity, the professor wants to know how many students get a specific grade x. Denote the number of students as n, which is assumed to be a power of 2. Take A and x as input, your task is to design a divide and conquer algorithm such that it outputs the number of students who get grade x. Explain your design with words (no pseudocode!) and justify its correctness. Stat and analyse its runtime. Faster (and correct) solutions are worth more credit.
