Python: Compute the depth of groups of matched nested parentheses separated by parentheses

Python Programming Puzzles: Exercise-98 with Solution

Depth of Matched Parentheses Groups

Given a string consisting of groups of matched nested parentheses separated by parentheses, write a Python program to compute the depth of each group.

Input: (()) (()) () ((()()())) 

Output:
[2, 2, 1, 3]
Input: () (()) () () () ()

Output:
[1, 2, 1, 1, 1, 1]
Input: (((((((()))))))) () (()) ((()()()))

Output:
[8, 1, 2, 3]

Sample Solution:

Python Code:

# License: https://bit.ly/3oLErEI

# Function to calculate the depth of groups of matched nested parentheses
def test(parens):
    # Split the input string into individual parentheses groups
    # and calculate the depth of each group
    return [len(s.split(')')[0]) for s in parens.split()]

# Test cases with different strings of parentheses
parentheses = '(()) (()) () ((()()())) '
print("Parentheses strings:", parentheses)
print("\nDepth of groups of matched nested parentheses separated by parentheses:")
print(test(parentheses))

parentheses = '() (()) () () () ()'
print("Parentheses strings:", parentheses)
print("\nDepth of groups of matched nested parentheses separated by parentheses:")
print(test(parentheses))

parentheses = '(((((((()))))))) () (()) ((()()()))'
print("Parentheses strings:", parentheses)
print("\nDepth of groups of matched nested parentheses separated by parentheses:")
print(test(parentheses))

Sample Output:

Parentheses strings: (()) (()) () ((()()())) 

Depth of groups of matched nested parentheses separated by parentheses:
[2, 2, 1, 3]
Parentheses strings: () (()) () () () ()

Depth of groups of matched nested parentheses separated by parentheses:
[1, 2, 1, 1, 1, 1]
Parentheses strings: (((((((()))))))) () (()) ((()()()))

Depth of groups of matched nested parentheses separated by parentheses:
[8, 1, 2, 3]
