ALGORITHM-
Step-1 Start
Step-2 Take a character for printing and limit for printing it no. of times.
Step-3 Initialization of variables.
Step-4 Run the loop for printing the no. of lines for square.
Step-5 If loop variable is equal to first value (i.e. 0) or last value {i.e. (limit-1)}
Then proceed to step 6 else to step 7.
Step-6 Run the loop for printing the first and last line of square only.
Step-7 Print the character only.
Step-8 Run the loop for giving the spaces inside the square.
Step-9 Print the character.
Step-10 Change the line.
Step-11 Run the loop for the lambda formation (present below the square).
Step-12 Print the character.
Step-13 Run the loop for printing the spaces.
Step-14 Print the spaces in ascending order.
Step-15 Print the character outside the space loop once again.
Step-16 Change the line.
