leet-chaser 0.1.0

Run LeetCode-style Python solutions against local TOML test cases.

Leet-Chaser

本地运行 leetcode solution 的命令行框架。

使用方法

STEP 1: 初始化题目目录

leet-chaser init two-sum
cd two-sum

命令会在当前目录创建一个题目文件夹：

two-sum/
├── solution.py
└── cases.toml

STEP 2: 编写 solution.py

from typing import List


class Solution:
    def twoSum(self, nums: List[int], target: int) -> List[int]:
        seen = {}
        for index, num in enumerate(nums):
            rest = target - num
            if rest in seen:
                return [seen[rest], index]
            seen[num] = index
        return []

STEP 3: 填写 cases.toml

entrypoint 是 solution 里的入口方法名。input 是传给入口方法的位置参数数组，output 是期望返回值。

entrypoint = "twoSum"

[[cases]]
input = [[2, 7, 11, 15], 9]
output = [0, 1]

[[cases]]
input = [[3, 2, 4], 6]
output = [1, 2]

[[cases]]
input = [[3, 3], 6]
output = [0, 1]

STEP 4: 运行验证

leet-chaser run .
