Leetcode 1: Two Sum

  Leetcode Link: https://leetcode.com/problems/two-sum/ 1. Problem Statement (Simple Explanation) You are given: An array of integers nums An integer target You need to  return the indices of two numbers in the array  such that: Conditions: Each input has  exactly one solution . You  cannot use the same element twice . You can return the answer in  any order . 2. Examples Example 1 Input:                                    nums = [2, 7, 11, 15], target = 9 Output:                                 [0, 1] Explanation:                     nums[0]+nums[1]=2+7=9              So we return [0, 1]. Example 2 Input:           ...

Leetcode 3: Longest Substring Without Repeating Characters

  Leetcode Link 1. Problem Statement (Simple Explanation) You are given a string s. You need to find the length of the longest substring of s that does not  contain any repeated characters. A substring is a contiguous sequence of characters in the string. You must return an integer length, not the substring itself. 2. Examples Example 1 Input: s = "abcabcbb" Output: 3 Explanation: Some substrings without repeating characters: "abc", "bca", "cab"The longest length is 3. Example 2 Input: s = "bbbbb" Output: 1 Explanation: All substrings that are valid are just "b". The longest length is 1. Example 3 Input:   s = "pwwkew" Output:   3 Explanation: Possible substrings without repetition: "pw", "wke", "kew". "wke" or "kew" have length 3. "pwke" is not valid because it’s not contiguous in the original string (p and k are separated by ww). Constraints...

Leetcode 2: Add Two Numbers

Leetcode Link: https://leetcode.com/problems/add-two-numbers/ 1. Problem Statement (Simple Explanation) You are given  two non-empty linked lists , l1 and l2, that represent two non-negative integers. Each node contains a  single digit . The digits are stored in  reverse order  (i.e., the 1’s digit is at the head). You need to  add the two numbers  and return the  sum as a linked list , also in reverse order. You can assume: There are  no leading zeros , except when the number itself is 0. 2. Examples Example 1 Input:                l1 = [2,4,3]                l2 = [5,6,4]           Interpreting linked lists as numbers (reverse order): l1 represents 342 l2 represents 465 Output:                [7,0,8] Explanation:        ...
