87. Number Capper

Write a Python program to cap a number within the inclusive range specified by the given boundary values x and y.

• If num falls within the range (a, b), return num.
• Otherwise, return the nearest number in the range.

Sample Solution:

Python Code:

def clamp_number(num, a, b):
  return max(min(num, max(a, b)), min(a, b))
 
print(clamp_number(2, 4, 7))
print(clamp_number(1, -1, -4))
print(clamp_number(22, -10, 10))
print(clamp_number(20, 1, 10))
print(clamp_number(5, 1, 20))
print(clamp_number(1, 10, 20))

Sample Output:

4
-1
10
10
5
10

• Write a Python program to cap a number within a given range by returning the lower bound if it is less than the minimum or the upper bound if it exceeds the maximum.
• Write a Python function that accepts a number and two boundary values and returns the number capped to that range, then test it with multiple examples.
• Write a Python script to process a list of numbers and apply capping based on given minimum and maximum values, then print the resulting list.
• Write a Python program to prompt the user for a number and boundaries, cap the number accordingly, and print the result using conditional expressions.
