3. (a) (b) Write a program whose input is an array A and a number x. The program should print the number of occurrences of x in A. You may not use recursion for this particular task. Write a recursive program for the same task as in (a). am(5 marks) bluo(5 marks) Write a program whose input is an array A and the output is YES if A contains an element occurring only once and NO otherwise. For instance, the answer for A = [2, 7, 7, 2, 8, 7, 8] should be NO because each element occurs at least twice, whereas the answer for A= [2, 7, 4, 7, 2, 8, 8] is YES because 4 occurs only once.
