Week 6: Programming Assignment 1 - Matrix

Due on 2021-09-09, 23:59 IST

Given two integers r and c, indicating the number of rows and columns, print a two-dimensional matrix such that the elements of the matrix are in an increasing sequence from 1 to rXc, in a row-major order.

Input Format:

First line of the input contains two space separated integers indicating the rows and columns

Output Format:

Display r lines indicating the elements of the Matrix

Example:

Input:

3 3

Output:

1 2 3

4 5 6

7 8 9

--Solution--  

n=input().split() a=0 for i in range(int(n[0])): for j in range(int(n[1])): a+=1 print(a,end='') if (j+1!=int(n[1])): print(' ',end='') if (i+1!=int(n[0])): print('\n',end='')

Week 6: Programming Assignment 2 - Number Triangle I

Due on 2021-09-09, 23:59 IST

Given an integer input 'n', print a number triangle of n lines as shown in the example.

--Solution-- 

n=int(input()) for i in range(1,n+1): for j in range(1,i+1): print(i,end='') if i!=n: print()

Week 6: Programming Assignment 3 - Symmetric Matrix

Due on 2021-09-09, 23:59 IST

Given a N X N square matrix, determine if it is a Symmetric Matrix.

Input Format:

The first line of the input contains an integer N which represents the number of rows and the number of columns.

Next N lines represent the elements of the matrix.

Output Format:

Print Yes or No

Example:

Input:

3

1 -2 3

-2 3 1

3 1 2

Output:

Yes

--Solution--  

M = int(input()) mat = [] for i in range(M): a =[] b=input().split() for j in b: a.append(int(j)) mat.append(a) def transpose(mat,B): for i in range(M): for j in range(M): B[i][j] = mat[j][i] B = [[0 for x in range(M)] for y in range(M)] transpose(mat, B) if(B==mat): print('Yes',end='') else: print('No',end='')
