Question

Procedure PROCX: You are given a sequence of digits x as input. You will return a sequence of digits as output. 1. Group the digits in x into pairs starting from the right. (If x has an odd number of digits, the leftmost group will only have a single digit in it) 2. Start with u, v, bot, top, and uide all having an initial value of o. 3. Then, working your way from left to right on the groups in x, repeat the following: a. Set bot to (bot - u) (the next group from x). b. Set side to 2 x top. c. Set o to the largest single digit such that v x (side v) d. Set u to vx (side'v). e. Set top to top "v. bot 4 The answer to return is the final value of top.

Explanation / Answer

the procx program is calculating square root of number, please find the trace below

Trace

group from x=13

bot=013

side=0

v=3

u=9

top=03

group from x=76

bot=476

side=6

v=7

u=469

top=037

group from x=41

bot=741

side=74

v=1

u=741

top=0371

ans=371

ans 371*371=137641
