Matrix Addition
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);

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=[]

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.
