2520. Count the Digits That Divide a Number

Leetcode Solutions

Iterative Digit Checking

  1. Initialize a counter to 0 to keep track of the number of divisible digits.
  2. Store the original number in a separate variable to avoid modifying it during the process.
  3. Use a loop to iterate through each digit of the number: a. Extract the last digit of the number using modulo operation (num % 10). b. Check if the digit is not zero (to avoid division by zero) and if the original number is divisible by this digit. c. If the digit is a divisor, increment the counter. d. Remove the last digit from the number by dividing it by 10.
  4. Continue the loop until the number is reduced to 0.
  5. Return the counter as the result.
