Question

Дан фрагмент кода программы. a=1 b=1 while(a<=...): a+=1 b+=5 Определи, какое число нужно поставить вместо многоточия, чтобы цикл выполнился ровно 3 раза. 3 4 5 6

Answer 1

3

a=1

While(a <= 3) true

a +=1 = 2

while (a<= 3) true

a +=1 = 3

while (a <=3) true

a +=1 = 4

while (a<=3) false

Answer 2

Code Fragment Analysis

The given code fragment appears to be a snippet of a Python program. It involves a while loop and the manipulation of variables `a` and `b`.

Determining the Value for the While Loop

To determine the value that needs to be placed instead of the ellipsis to make the loop execute exactly 3 times, we can analyze the code.

The initial values of `a` and `b` are set to 1. Then, the while loop increments `a` by 1 and `b` by 5 in each iteration.

Calculation

To find the value that needs to replace the ellipsis, we can calculate the number of iterations required for the loop to execute 3 times.

Let's calculate the number of iterations: - First iteration: a=2, b=6 - Second iteration: a=3, b=11 - Third iteration: a=4, b=16

So, the value that needs to replace the ellipsis to make the loop execute exactly 3 times is 4.

Therefore, the correct answer is 4.
