Can you provide a code to print all palindromic paths from top left to bottom right in a matrix and the other steps required given the following:
Print all palindromic paths from top left to bottom right in a matrix | Python 3 program to print all palindromic paths from top left to bottom right in a grid ..
i and j are row and column indexes of current cell ( initially these are 0 and 0 ) ..
If we have not reached bottom right corner , keep exlporing.
If we reach bottom right corner , we check if the path used is palindrome or not ..
Driver code"
How can the above be solved in Python?
