Maximum Nesting Depth of the Parentheses
The task requires us to find the maximum depth of parentheses in a given string. We can solve this problem using a stack-like approach without actually using a stack. We can use a counter to mimic the stack’s behavior.
Here is the Python code:

In this code, we initialize curr_depth
and max_depth
to zero. Then we iterate over each character in the string. If the character is an opening parenthesis, we increment curr_depth
and update max_depth
if curr_depth
is greater. If the character is a closing parenthesis, we decrement curr_depth
. In the end, max_depth
contains the maximum depth of parentheses in the string.
