📝 Walkthrough

Walkthrough

Adds Solution in recap/may_2026/easy.py with twoSum, isPalindrome, and romanToInt; updates Go RomanToInt to a forward-scan algorithm; adds a new parameterized two-sum test and augments existing tests to assert the new implementations.

Changes

Easy problems: implementations, Go converter update, and tests

Layer / File(s)	Summary
Core Implementation — Python recap/may_2026/easy.py	Adds class Solution with twoSum(self, nums: List[int], target: int) -> List[int) using a single-pass complement hash-map; isPalindrome(self, x: int) -> bool) using numeric reversal; romanToInt(self, s: str) -> int) using forward-scan with lookahead.
Converter Logic — Go Go/leetcode.go	Reworks RomanToInt to a forward-scanning add/subtract implementation and adds a block comment explaining the approach.
Tests — new tests/test_easy_recap.py	Adds parameterized test_two_sum covering basic pairs, duplicates, zeros, no-match cases; instantiates Solution and asserts sorted(result) == sorted(expected).
Tests — updated tests/test_leetcode.py	Imports recap.may_2026.easy.Solution and adds assertions that its isPalindrome and romanToInt outputs match expected results alongside existing checks.

Poem

🐰 I hopped through numbers, quick and spry,
Counting complements beneath the sky,
I mirrored digits, checked each line,
Roman symbols turned to sums just fine,
A little hop — the tests now sigh with joy.

Docstring Coverage	⚠️ Warning	Docstring coverage is 57.14% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Title check	❓ Inconclusive	The title 'recap: with easy starts' is vague and does not clearly convey the specific changes made in the pull request, which adds a Solution class with multiple problem solutions (twoSum, isPalindrome, romanToInt).	Consider using a more descriptive title like 'Add Solution class with twoSum, isPalindrome, and romanToInt implementations' to clearly communicate the main changes.
