The flowchart describes an algorithm that increments a variable i and updates a variable x until x is greater than or equal to 25. Let's break down the flowchart step by step:

  • Начало (Start): The algorithm begins.
  • Список данных (Data List): Initializes two variables:
  • i as an integer
  • x as a real number
  • Initialization: Sets initial values:
  • i := 1
  • x := 10
  • Loop: A loop that continues as long as x is less than 25.
  • Inside the loop:
  • i := i + 1 (increments i by 1)
  • x := x + 0.1 * x (increments x by 10% of its current value)
  • Condition: Checks if x >= 25.
  • If Нет (No), the loop continues.
  • If Да (Yes), the algorithm proceeds to the next step.
  • Output: Outputs the value of i.
  • Конец (End): The algorithm ends.

Here’s how the algorithm behaves in terms of code-style execution:


i = 1
x = 10

while x < 25:
 i = i + 1
 x = x + 0.1 * x

print(i)

The algorithm essentially calculates how many iterations it takes for x, starting at 10 and increasing by 10% each time, to reach or exceed 25, and then outputs the corresponding value of i.
