Implement Strassen's algorithm to multiply two 2x2 matrices code example

Example: Implementation of Strassen’s algorithm to multiply two square matrices

$ gcc strassen.c -o strassen
$ ./strassen
 
Enter the 4 elements of first matrix:
1 2
3 4
Enter the 4 elements of second matrix: 
5 6 
7 8
The first matrix is
 
1	2	
3	4	
The second matrix is
 
5	6	
7	8	
After multiplication using Strassen's algorithm
 
19	22	
43	50
