Enter the value of Row-1 & Column-1: 0
Enter the value of Row-1 & Column-2: 0
Enter the value of Row-1 & Column-3: 0
Enter the value of Row-1 & Column-4: 5

Enter the value of Row-2 & Column-1: 0
Enter the value of Row-2 & Column-2: 2
Enter the value of Row-2 & Column-3: 0
Enter the value of Row-2 & Column-4: 0

Enter the value of Row-3 & Column-1: 0
Enter the value of Row-3 & Column-2: 0
Enter the value of Row-3 & Column-3: 0
Enter the value of Row-3 & Column-4: 4

Enter the value of Row-4 & Column-1: 0
Enter the value of Row-4 & Column-2: 0
Enter the value of Row-4 & Column-3: 0
Enter the value of Row-4 & Column-4: 1

The Vector Form is:

1 4 5
2 2 2
3 4 4
4 4 1
Created Sparse Matrix from Vector Form:
0 0 0 5
0 2 0 0
0 0 0 4
0 0 0 1
