CTS & Wipro Automata Test 13 - 19th Sep

 

Rotate Matrix Anticlockwise

The program must accept an integer matrix of size NxN as the input. The program must rotate the given matrix by 90 degree in anticlockwise direction. Finally, the program must print modified matrix as the output.

Boundary Condition(s):

1 <= N <= 100

1 <= Matrix Element Value <= 9999999

Input Format:

The first line contains the value of N.

The next N lines contain N integers separated by space(s).

Output Format:

The first N lines contain N integers of the modified matrix separated by space(s).

Python:

n=int(input())

l=[];t=[]

for i in range(n):

    l.append(list(map(int,input().split())))

for i in l:

    t.append(i[::-1])

m=zip(*t)

for i in m:

    print(*i)

Product of Matrix and it's Transpose Program In Python

The program must accept two positive integers M and N as the input. The program must generate a 4×4 integer matrix by using the following conditions,

– The first element of the matrix must be the value of M.

– The successive elements are obtained by adding N to the current element.

Finally, the program must print the product of the generated matrix and it’s transpose.

Note:  For the matrix product, the elements in the same positions are multiplied to get the resultant matrix.

Boundary Condition(s):

1 <= M, N <= 100

Input Format:

The first line contains the values of M and N separated by a space.

Output Format:

The first four lines contain four integers in the product of the generated matrix and it’s transpose.

Example Input/Output 1:

Input:

4 1

Output:

16 40 72 112

40 81 130 187

72 130 196 270

112 187 270 361

Explanation:

The generated matrix as per the conditions mentioned above is

4 5 6 7

8 9 10 11

12 13 14 15

16 17 18 19

The transpose of the generated matrix is

4 8 12 16

5 9 13 17

6 10 14 18

7 11 15 19

The product of the generated matrix and it’s transpose is

16 40 72 112

40 81 130 187

72 130 196 270

112 187 270 361

Input:

3 5

Output:

9 184 559 1134

184 784 1584 2584

559 1584 2809 4234

1134 2584 4234 6084

Python:

m,n=map(int,input().split())

k=m;p=[]

for i in range(4):

    l=[]

    for j in range(4):

        l.append(k);k+=n

    p.append(l)

a=p

r=[[0 for i in range(4)] for j in range(4)]

for i in range(4):

    for j in range(4):

        r[j][i]=a[i][j]

for i in range(4):

    for j in range(4):

        print(r[i][j]*p[i][j],end=' ')

    print()
