The Pseudocode. Create a hash map that has ‘closed parentheses’ as the keys and their matching ‘open parentheses’ as the value. Create a stack. Loop through the string.

WebThis algorithm is fairly simple: we just iterate a counter across the sequence. Starting from 0, we increment it at each sighting of a left-parenthesis, and decrement it at each right-parenthesis. If the counter never goes negative and its final value is 0, then the sequence is matched. In terms of implementation, we’ll actually use the type int WebFigure 4: Matching Parentheses ¶ Once you agree that a stack is the appropriate data structure for keeping the parentheses, the statement of the algorithm is straightforward. Starting with an empty stack, process the parenthesis strings from left to right. If a symbol is an opening parenthesis, push it on the stack as a signal that a ...
