If I get an instruction to remove a disk and there are no disks remaining, I have an unbalanced number of parentheses. All that mentioning of "stacks" should give you a clue here: the data structure we wanna use in solving this is, unsurprisingly, a *stack*. The thing about a stack ...
This paper examines the possibilities of applying Catalan numbers in cryptography. It also offers the application of appropriate combinatorial problems (Ballot Problem, Stack permutations and Balanced Parentheses) in encryption and decryption of files and plaintext. The paper analyzes the properti...
Zip the open and closed parentheses tuple into the dictionary using the zip function. Create an empty stack to track the open parentheses and iterate through the given string using a while loop. If the iterated value is present in the open tuple, append it to the stack. Check if the stack...
