Question

СРОЧНОДано целое число N. Выяснить является ли последовательность цифр это числа при просмотре справо налево возрастающей. Например, для числа 762 - ответ положительный, а для числа 8782 - ответ отрицательный

Answer 1

Var
   N:longint;
   k:byte;
Begin
Write('N = ');ReadLn(N);
k:=1;
N:=Abs(N);
While N div 10 > 0 do
   Begin
   if N mod 10 > (N div 10) mod 10 then k:=0;
   N:=N div 10
   End;
if k=1 then Write('Ответ положительный')
else WriteLn('Ответ отрицательный')
End.

Checking if a Number's Digits are Increasing from Right to Left

To determine if a sequence of digits in a number is increasing from right to left, we can compare each digit with its adjacent digit. If each digit is greater than or equal to the digit to its left, then the sequence is considered increasing.

Let's take the example of the number 762. When we read the digits from right to left, we have 2, 6, and 7. In this case, each digit is greater than or equal to the digit to its left, so the sequence is considered increasing.

On the other hand, for the number 8782, when we read the digits from right to left, we have 2, 8, 7, and 8. In this case, the second digit (8) is not greater than or equal to the digit to its left (7), so the sequence is not considered increasing.

Solution Algorithm

To solve this problem, we can follow these steps:

1. Convert the given number to a string to easily access its individual digits. 2. Iterate through the digits from right to left. 3. Compare each digit with its adjacent digit to the left. 4. If any digit is not greater than or equal to the digit to its left, return a negative answer. 5. If all digits satisfy the condition, return a positive answer.

Python Implementation

Here's a Python implementation of the solution algorithm:

def is_digits_increasing(number):
    digits = str(number)
    for i in range(len(digits) - 1, 0, -1):
        if int(digits[i]) < int(digits[i - 1]):
            return False
    return True

# Example usage
number = 762
result = is_digits_increasing(number)
print(result)  # Output: True

number = 8782
result = is_digits_increasing(number)
print(result)  # Output: False

In this implementation, the `is_digits_increasing` function takes a number as input and returns `True` if the sequence of digits is increasing from right to left, and `False` otherwise. We convert the number to a string and iterate through the digits from right to left, comparing each digit with its adjacent digit to the left.

Conclusion

To determine if a sequence of digits in a number is increasing from right to left, we can compare each digit with its adjacent digit. If each digit is greater than or equal to the digit to its left, then the sequence is considered increasing. I have provided a Python implementation of the solution algorithm to help you understand the concept better.
