Introduction to the Coding Question

In this article, we will be discussing a coding question that is recently asked in a placement exam. The question involves finding the largest number divisible by 90 that can be formed using any number of elements from an array containing only 0s and 5s.

Understanding the Problem Statement

The problem requires us to find the maximum possible number that can be made using the elements of the array, such that the number is divisible by 90. We need to arrange the array elements in a specific order that ensures the maximum divisibility by 90.

Divisibility Rules of 9 and 10

To determine whether a number is divisible by 9, we can check if the sum of its digits is divisible by 9. Similarly, for divisibility by 10, the number should end with a 0.

Approach to solve the problem

To solve the problem, we will follow the following steps:

  1. Traverse the array and count the number of 0s and 5s.
  2. Handle special cases where there are no 0s or 5s.
  3. Check the divisibility of the number formed by considering all the 5s.
  4. Reduce the count of 5s if required to ensure divisibility by 90.
  5. Print the maximum possible number that satisfies the divisibility condition.

Handling special cases

There are three possible scenarios that can occur in our code:

  1. If the count of 0s in the array is 0, it means there are only 5s. In this case, we cannot form a number divisible by 90, so we return -1.
  2. If the count of 5s in the array is less than 9, we cannot form a number divisible by 90. In this case, we print 0.
  3. If the above conditions are not met, we proceed with further calculations.

Implementing the code logic

In the code, we initialize the count of 0s and 5s as 0. Then, we traverse the array to count the 0s and 5s. Based on the counts, we handle the special cases. If none of the special cases is encountered, we proceed with the while loop to print the maximum possible number.

Explaining the code step-by-step

We start by initializing the count of 0s and 5s as 0. Then, we traverse the array and count the number of 0s and 5s. After counting, we check the special cases and return the output accordingly. If the special cases are not met, we go through the while loop and print the numbers as per the logic explained earlier.

Running test cases and analyzing the output

To ensure the correctness of our code, we run multiple test cases and analyze the output. We include scenarios with different array sizes and element combinations to cover all possible cases. By examining the output, we can verify if our code is functioning as expected.

Conclusion

In conclusion, this article provided a detailed explanation of how to solve a coding question regarding finding the maximum number divisible by 90 using elements from an array. We discussed the problem statement, approach, code logic, and test cases. By following the steps and understanding the logic, You can easily solve similar coding problems.
