Modified the Leetcode code for ListNode by including the dunder "repr" method. This is for when you want to print a ListNode to see what its value and next node(s). This is for when you want to print a ListNode to see what its value and next node(s).

2019年11月17日 · Lately, I started "leetcode" for studying programming. ... I want to make TreeNode from a list by Python ...

40ms difference is way too low to take seriously. The python runtime takes about that long to fire up. Architectural changes LeetCode might have made to their testing suit, python interpreter, etc. are the most likely suspect for this performance disparity.

2020年2月10日 · Here is the leetcode question: Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note: The number of elements initialized in nums1 and nums2 are m and n respectively. You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. Example:

2021年9月24日 · Trying to solve LeetCode "Add Two Numbers". You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes

2016年3月5日 · Let me first clarify that I suggested set assuming the matrix m might be sparse, but even for the dense case I would prefer a nested list of 0/1 integers to a set, because conceptually that is the structure I want to represent, and in Python you often optimize for readability rather than anything else.

2023年12月13日 · I'm attempting to address Leetcode problem 2. Add Two Numbers: You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list.

2018年2月4日 · Java code to merge two sorted Arrays Given two sorted arrays, the task is to merge them in a sorted manner. Input: arr1[] = { 1, 3, 4, 5}, arr2[] = {2, 4, 6, 8 ...

So I am a beginner in Competitive Coding and started practicing Leetcode questions. The question is as follows: Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice.

2021年8月3日 · The question in Leetcode doesn't have the argument memo = {}. This is from LC code. def combinationSum4(self, nums: List[int], target: int) -> int: Since you are changing the functions arguments, it works for you only in PyCharm or Jupyter. But Leetcode will only pass the required arguments i.e nums and target and not memo = {}.
