Certification: Basic Level Accuracy: 51.31% Submissions: 191 Points: 5

Write a Python program that converts a decimal number to its hexadecimal representation.

Example 1
    
  
  • Input: 10
    • 
  
  • Output: "a"
    • 
  
  • Explanation: 
    
      
      
    • Step 1: Take the input number 10.
      • 
      
    • Step 2: Convert 10 to its hexadecimal representation, which is "a".
      • 
      
    • Step 3: Return "a" as the result.
      •

Example 2
    
  
  • Input: 255
    • 
  
  • Output: "ff"
    • 
  
  • Explanation: 
    
      
      
    • Step 1: Take the input number 255.
      • 
      
    • Step 2: Convert 255 to its hexadecimal representation, which is "ff".
      • 
      
    • Step 3: Return "ff" as the result.
      •

Constraints
    
  
  • 0 ≤ number ≤ 10^9
    • 
  
  • Return the hexadecimal representation as a lowercase string without the "0x" prefix
    • 
  
  • Time Complexity: O(log n), where n is the input number
    • 
  
  • Space Complexity: O(log n)

Solution Hints

    
  
  • Use hex() function: hex(number)[2:]
    • 
  
  • Use format(): format(number, 'x')
    • 
  
  • Create a hex digit mapping and use iterative division
    • 
  
  • Use recursion with hex mapping: def to_hex(n): return "" if n == 0 else to_hex(n // 16) + "0123456789abcdef"[n % 16]
    •

The following are the steps to convert a decimal number to hexadecimal:

  • Take a decimal number as input.  

  •  Use `hex(num)[2:]` to get the hexadecimal representation.  

  •  Print the result.  

  •  Check with numbers like `255` (should give `FF`).
