Infix expression has balanced parenthesis or not, Data Structure & Algorithms

Assignment Help:

Q. By making use of stacks, write an algorithm to determine whether the infix expression has balanced parenthesis or not.                                                                                                               

Ans.

Algorithm parentheses is written below

This specific algorithm reads a source program and parses it to make sure all opening -closing parenthesis are systematically paired

1. loop (more data)

read (character)

if (character is not a closing parenthesis)

pushstack ( stack, character)

else

if (character is closing parenthesis)

popstack (stack, token)

while ( token is not an opening paranthesis)

popstack (stack, token)

endwhile end if

end if end loop

if (not emptystack (stack))

print (Error: opening parenthesis not matched)

end parseparens.
