The loop continues until the value of Num becomes zero. At that point, Count contains the number of 1's that were in the original number. Exercise 5: Just as it is possible to multiply by adding over and over, it is possible to divide by subtracting over and over. Suppose you want to know how many times N1 goes into N2. Start with N2 and subtract N1 repeatedly until the answer is less than N1. The number of subtractions you performed is the number of times that N1 goes into N2. For example, you can compute that 4 goes into 14 three times by computing 14 - 4 - 4 - 4 = 2 . (The number 2 that you end up with here is the remainder when 14 is divided by 4.) Write a program to compute how many times a number N1 goes into another number N2. Your program will be somewhat similar to the sample program "MultiplyByAdding.txt." You still need a loop, and you still need to count how many times that loop is executed

high pressure. Rochefort and Dyer alternated 12 hours on, 12 hours off. Speed was emphasized. As the meaning of a codegroup became known in the Combat Intelligence Unit, whether through its own efforts or by a helpful message from another unit, the codegroup and its meaning were punched on an I.B.M. card and stored in the machine. When an intercept came in, a clerk would punch its codegroups on I.B.M. cards and feed them in. The machine automatically made the run of repeated subtractions and the check of its mechanized difference "books" necessary to find the identical remainders, and then, with human guidance, the runs to reconstruct the relative additive sequence, correct it to the absolute sequence, and strip it from the encicode message. This machine would then compare the placode groups with the decode cards in its storage and print out the plaintext for whatever decode cards it had. Presumably it would also print out the various possibilities in the
