Practice exercise - Print the Smallest Number in a 3*3 Matrix

The video tutorial explains how to find the minimum number in a 3x3 matrix using nested loops. It covers initializing a multidimensional array, implementing logic to traverse the matrix, and debugging the code. The tutorial concludes with an assignment to find the maximum number in the matrix.

What is a common interview question related to matrices?

• Finding the maximum number

• Finding the average of elements

• Finding the minimum number

• Finding the sum of all elements

How is a multidimensional array declared in the given example?

• Using two braces

• Using single braces

• Using square brackets

• Using parentheses

What is the initial assumption made about the minimum number in the matrix?

• Zero is the minimum

• The middle element is the minimum

• The first element is the minimum

• The last element is the minimum

Which loop is used to traverse the rows of the matrix?

• Outer for loop

• Do-while loop

• While loop

• Inner for loop

What is the initial value assigned to the 'min' variable?

• The last element of the matrix

• Zero

• The first element of the matrix

• A random number

What is the purpose of debugging the code?

• To write new code

• To compile the code

• To analyze and verify the code logic

• To delete unnecessary code

What happens when a smaller number is found during the traversal?

• It is multiplied by the current minimum

• It is added to the list

• It is swapped with the current minimum

• It is ignored

What is the significance of the 'min' variable in the code?

• It stores the maximum value

• It stores the smallest value found

• It stores the sum of values

• It stores the average value

What is the final task assigned to the students?

• Find the average of the matrix

• Find the median of the matrix

• Find the maximum number in the matrix

• Find the sum of the matrix

What should be done if the maximum number task is not completed?

• Submit an incomplete task

• Redo the minimum number task

• Ask for help in the discussion board

• Ignore it
