Question

Raju has a square shaped puzzle made up of small square pieces containing numbers on them. He wants to rearrange the puzzle by changing the element of a row into a column element and column element into a row element without altering the shape of the puzzle. Help raju to solve this puzzle. FUNCTIONAL REQUIREMENTS: int** createArray(int,int); int getElement(int**,int,int); int addMatrix(int**,int**,int**,int,int);

Answer 1

Matrix Addition Program in Python, using the functions given in the data provided.

Language used : Python Programming

Program : (DYNAMIC, YOU CAN PROVIDE ANY NO.OF ROWS AND COLUMNS)

def createarray(a,b):

  x=int(input())       #no.of rows

 y=int(input())      #no.of columns

 getelement(x,y,a,b)

def getelement(x,y,a,b):

 for i in range(x*y):

     a.append(int(input()))

 for i in range(x*y):

     b.append(int(input()))

 addmatrix(x,y,a,b)

def addmatrix(x,y,a,b):

 for i in range(x):

     j=i*y

     for k in range(j,y+j):

         print(a[k]+b[k], end="  ")

     print()

a=[]

b=[]

createarray(a,b)

Input :

Output :

2     4

6     8

Explanation :

• Take to empty lists and pass them through createarray() function.

• Define a createarray() function, and ask the user to input row and column sizes.

• Then, pass sizes and lists (which acts as arrays now as we are going to take in only integer values : so they act as arrays of type int) through function call of function getelement().

• Create a function getelement() which takes in row*column size of elements into each arrays (2x2 matrix= 4 elements, 2x3 matrix = 6 elements).

• Once done, pass the elements filled lists, sizes through the function call addmatrix() that adds the corresponding elements of the two lists and prints them in a matrix form. That's it.
