Below are several scripts, each involving a while loop. Select each of the scripts in which the code inside the while loop is run exactly once. ✓a. 1 = [1, 1] while 4 not in 1: 1.append(sum(1)) b. 1 = [1] m = 1 i = 2 while len(1)<3: 1.append(i) m.append(1+1) i = 1+1 c. 1 = range (17, 97) while 1: 1 = = 1[20:-20] ✓ d. x = 100 while x>0: S = 0 for x in range(100, -1, -1): S = 5+1 ༣ ✓ f. e. 1 = [1] m = 1 i = 2 while m is 1: 1 = 1+[i] m = 1+[i+1] i = 1+1 f = lambda x: lambda y: while f!=0: f = f(0)

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

(Program) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters, such as zerocount, onecount, twocount, and so forth, to 0. Then generate a large number of pseudorandom integers between 0 and 9. Each time 0 occurs, increment zerocount; when 1 occurs, increment onecount; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of time they occurred.
