Selenium WebDriver with Java - Basics to Advanced and Frameworks - Practice Exercise - Cisco Interview Question on Array

The video tutorial explains how to solve a matrix problem where the task is to find the minimum number in a row and then identify the maximum number in the same column. The instructor provides a step-by-step approach to developing an algorithm, followed by a detailed code implementation. Examples are used to clarify the problem, and debugging techniques are demonstrated to ensure the code works correctly.

What is the primary task in the matrix problem discussed?

• Find the maximum number in the matrix.

• Identify the minimum number and find the maximum in its column.

• Calculate the sum of all numbers in the matrix.

• Determine the average value of the matrix.

In the given problem, what should be done after identifying the minimum number in a row?

• Swap the minimum and maximum numbers.

• Calculate the difference between the minimum and maximum numbers.

• Locate the maximum number in the same column as the minimum number.

• Find the minimum number in the entire matrix.

What is the first step in the algorithm to solve the matrix problem?

• Sort the matrix in ascending order.

• Identify the maximum number in the matrix.

• Calculate the sum of the matrix elements.

• Find the minimum number in the matrix.

How is the column of the minimum number identified in the algorithm?

• By directly accessing the column index.

• By sorting the matrix columns.

• By calculating the average of the column.

• By using a nested loop to traverse the matrix.

What is the purpose of the while loop in the code implementation?

• To iterate through all columns of the matrix.

• To sort the elements of the identified column.

• To traverse the identified column to find the maximum number.

• To calculate the sum of the identified column.

Why is the column value kept constant in the while loop?

• To calculate the average of the column.

• To sort the column elements.

• To ensure the loop checks all columns.

• To focus on finding the maximum number in the identified column.

What is the expected output when the minimum number is found in the last column?

• The sum of the last column.

• The minimum number in the last column.

• The maximum number in the last column.

• The maximum number in the first column.

What should be done if the maximum number is not greater than the current maximum in the loop?

• End the loop.

• Restart the loop.

• Swap the numbers.

• Continue to the next iteration.

What is the significance of debugging in the code implementation?

• To ensure the code runs faster.

• To verify the logic and correctness of the solution.

• To add more features to the code.

• To reduce the size of the code.

What is the final step in the debugging process?

• Print the entire matrix.

• Print the sum of all matrix elements.

• Print the maximum number found in the identified column.

• Print the minimum number in the matrix.
