Easy Find

2D ARRAY

1. Write a code to search for a value in the matrix and change it with user given value. Your code should give the position of that number too. User will give 2 inputs: 1.) What value to change/search and 2.) What is the new value.  
2.  WAP to transpose a square matrix.  
3. WAP to print all the prime numbers from a 2D array and find out their sum.  
4. WAP to display those elements of a two dimensional array which are divisible by 10. Also find their sum.  
5. WAP to find out the sum of negative, positive, odd and even integers separately from a two dimensional array. 
6. WAP to find out the product of two matrices. 
7. WAP to find out the sum and difference of two matrices. 
8. WAP to display the upper and lower triangle of a matrix. 
9. WAP to find out the sum of non diagonal elements.  
10. WAP to print the left and right diagonal of a square matrix and find out their sum separately. 
11. WAP to double all the elements of a matrix.  
12. WAP to find out the row sum and column sum of a two dimensional array of integers. 
13. WAP to display the values of a two dimensional array in the matrix form.
