Key Insights

The algorithm uses a loop where b is reduced each time until it reaches 1. If b is odd, a is added to T and b is decremented. If b is even, a is doubled and b is halved. This is similar to Russian Peasant Multiplication, efficiently calculating \(\mathrm{a × b}\) using addition, doubling, and halving. T accumulates the correct sum by only adding a when b is odd, and the process always finishes since b steadily decreases.

Step-by-Step Solution

Question 1: Finding the First Nonzero Value of T in the Algorithm

Complete Statement:

If 24 and 35 are entered as the values for a and b, respectively, then the first nonzero value of T is ______.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: 24 and 35 are entered as the values for a and b
  • Meaning: We start the process by setting \(\mathrm{a = 24}\) and \(\mathrm{b = 35}\).
  • Relation to Chart: These values are put into the flowchart at the 'Enter a and b' step.
  • Important Implications: These specific numbers will control how the loop and decisions operate.
• Statement Breakdown 2:
  • Key Phrase: first nonzero value of T
  • Meaning: We are to find the first value T takes on that is not zero, as the algorithm runs.
  • Relation to Chart: T starts at 0 and is only changed after certain operations depending on b's value.
  • Important Implications: We are looking for the exact value produced when T first is updated from its initial value.

What is needed: The value that T first takes when it becomes not zero after beginning the process with \(\mathrm{a = 24}\) and \(\mathrm{b = 35}\).

Solution:

• Condensed Solution Implementation:
  Trace the first step of the algorithm with \(\mathrm{a = 24}\) and \(\mathrm{b = 35}\), focusing on how and when T is changed from 0.
• Necessary Data points:
  Initial values: \(\mathrm{a = 24, b = 35, T = 0}\).
• Calculations Estimations:
  Since \(\mathrm{b = 35}\) is odd, the algorithm immediately computes \(\mathrm{T = T + a}\), so \(\mathrm{T = 0 + 24 = 24}\). This is T's first nonzero value.
• Comparison to Answer Choices:
  The answer choices likely include 24. This matches our result.

FINAL ANSWER Blank 1: 24

Question 2: Value of b After the Second Halving

Complete Statement:

If 35 and 27 are entered as the values for a and b, respectively, then after the process \(\mathrm{b = b/2}\) is completed for the second time, the value of b is ______.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: 35 and 27 are entered as the values for a and b
  • Meaning: We start by setting \(\mathrm{a = 35}\) and \(\mathrm{b = 27}\).
  • Relation to Chart: These are the starting values input into the algorithm.
• Statement Breakdown 2:
  • Key Phrase: after the process \(\mathrm{b = b/2}\) is completed for the second time
  • Meaning: We're to keep track of each execution of \(\mathrm{b = b/2}\) and determine the value after the 2nd time it happens.
  • Relation to Chart: \(\mathrm{b = b/2}\) occurs only when b is even, so we need to trace through the relevant steps and count these occurrences.

What is needed: The value of b immediately after the second time b is set to \(\mathrm{b/2}\) (i.e., the second time it is halved).

Solution:

• Condensed Solution Implementation:
  Simulate the algorithm step-by-step, specifically counting how many times b is halved and noting the resulting value after the second such event.
• Necessary Data points:
  Start: \(\mathrm{a = 35, b = 27, T = 0}\). Track each step until b is halved twice.
• Calculations Estimations:
  Step 1: \(\mathrm{b=27}\) is odd → \(\mathrm{T = T + a = 35, b = 26, a = 70}\). Step 2: \(\mathrm{b=26}\) is even → First halving: \(\mathrm{b = 13, a = 140}\). Step 3: \(\mathrm{b=13}\) is odd → \(\mathrm{T = T + a = 35+140=175, b = 12, a = 280}\). Step 4: \(\mathrm{b=12}\) is even → Second halving: \(\mathrm{b = 6, a = 560}\). The value of b after the second halving is 6.
• Comparison to Answer Choices:
  Answer choices likely include 6, matching our calculation.

FINAL ANSWER Blank 2: 6

Summary

For both blanks, careful tracking of the algorithm's steps yields the answers without running the entire process. For blank 1, the first update to T happens immediately, and for blank 2, counting the two occurrences of '\(\mathrm{b = b/2}\)' gives the answer. Understanding when conditions are met—like b being odd or even—helps solve these quickly.

Question Independence Analysis

The two blanks are independent: each uses different input values and asks about different variables or steps in the algorithm. Solving one does not inform or affect solving the other.
