Question
You will be given a 2-d Matrix, and you need to concatenate values of the row, let's say it as Array 'A', which will contain concatenated values of each row as each value.Now, you need to concatenate the values present in 'A'(in any order) so that the final concatenated number is the maximum of all numbers possible.Input FormatThe first input line contains an integer 'n' denoting the number of rows in the matrix.The second input line contains an integer 'm' denoting the number of columns in the matrix.Next, 'n' input lines contain 'm' space-separated integers denoting matrix elements.Output FormatOutput the final concatenated string.Constraints2 <= n <= 5002 <= m <= 5001<=matrix elements<=105Sample Input331 2 34 5 67 8 9Sample Output789456123ExplanationAfter concatenating the values of each row, we get : "123" , '456" , "789"Now there are many possibilities for concatenating the above 3 values as follows: "123456789" , "456123789" , "789456123" , etc.Out of all possibilities, only "789456123" is the maximum of all, hence this is our answer.
Solution
To solve this problem, you can follow these steps:
- First, read the number of rows 'n' and columns 'm' from the input.
- Create an empty list 'A'.
- For each row in the matrix, concatenate the elements of the row into a string and append it to 'A'.
- Sort the list 'A' in descending order. This is because we want to get the maximum possible number after concatenation.
- Finally, concatenate the strings in 'A' to get the final result.
Here is a Python code snippet that implements these steps:
n = int(input())
m = int(input())
A = []
for _ in range(n):
row = input().split()
A.append(''.join(row))
A.sort(reverse=True)
print(''.join(A))
This code reads the number of rows and columns, then reads each row, concatenates its elements into a string and appends it to 'A'. After reading all rows, it sorts 'A'
