2D ARRAYS QUESTIONS
Question 1 : Print the number of 7’s that are in the 2d array.
Example :
Input - int[][] array = { {4,7,8},{8,8,7} };
Output - 2
Question 2 : Print out the sum of the numbers in the second row of the “nums” array.
Example :
Input - int[][] nums = { {1,4,9},{11,4,3},{2,2,3} };
Output - 18
Question 3 : Write a program to Find Transpose of a Matrix.
What is Transpose?
Transpose of a matrix is the process of swapping the rows to columns. For a 2x3 matrix,
Matrix
a11 a12 a13
a21 a22 a23
Transposed Matrix
a11 a21
a12 a22
a13 a23
