Matrix Subtraction

• Problem Description

  
  Write a python program to create a NESTED LIST and subtract the two matrix. (Without Square Brackets)
  
  Hint:
  
  1. Input the number of rows and columns for First Matrix
  
  2. Input the number of rows and columns for Second Matrix
  
  3. Display the first matrix elements in Matrix format (Without commas and Square Bracket)
  
  4. Display the first matrix elements in Matrix format (Without commas and Square Bracket)
  
  5. Display the result of difference of two matrix (Without commas and Square Bracket)
