Matrix Script in Python - HackerRank Solution
Problem :
Neo has a complex matrix script. The matrix script is a N X M grid of strings.
It consists of alphanumeric characters, spaces and symbols (!,@,#,$,%,&).
If there are symbols or spaces between two alphanumeric characters of the decoded script, then Neo replaces them with a single space '' for better readability.
Neo feels that there is no need to use 'if' conditions for decoding.
Alphanumeric characters consist of: [A-Z, a-z, and 0-9].
Input Format :
The next N lines contain the row elements of the matrix script.
Constraints :
- 0 < N
- M < 100
Note: A 0 score will be awarded for using 'if' conditions in your code.
Output Format :
Print the decoded matrix script.
Sample Input :
7 3 Tsi h%x i # sM $a #t% ir!
Sample Output :
This is Matrix# %!
Explanation :
The decoded script is:
This$#is% Matrix# %!
So, the final decoded script is:
This is Matrix# %!

Hey, I am Parthe Omkar
sir when we run this code we get a /n in the end of output which is used for new line how can we remove it
#!/bin/python3
import math
import os
import random
import re
import sys
first_multiple_input = input().rstrip().split()
n = int(first_multiple_input[0])
m = int(first_multiple_input[1])
matrix = []
for _ in range(n):
matrix_item = input()
matrix.append(matrix_item)
encoded_string = "".join([matrix[j][i] for i in range(m) for j in range(n)])
pat = r'(?<=[a-zA-Z0-9])[^a-zA-Z0-9]+(?=[a-zA-Z0-9])'
print(re.sub(pat,' ',encoded_string))
r'(?<=\w)([\W]+)(?=\w)
