Course Description Video :
In this video we have solved Two sum problem using Java, which is most commonly asked interview question for experience as well as fresher.
The problem in two sum leetcode says : Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to the given required target.
You may assume that each input would have exactly one solution, and you may not use the same element twice at all.
You can return the answer in any order is the flexibility given in two sum leetcode problem.
Example 1 as per two sum leetcode :
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
Output: Because nums[0] + nums[1] == 9, we return [0, 1].
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.
You can return the answer in any order.
Example 1:
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
Output: Because nums[0] + nums[1] == 9, we return [0, 1].
Example 2:
Input: nums = [3,2,4], target = 6
Output: [1,2]
Example 3:
Input: nums = [3,3], target = 6
Output: [0,1]
Constraints:
WE have solved this two sum leetcode in three different ways and this oart contains one simple O(n^2) solution which we have reduced till O(2n) and O(n) also using MAP in next video. Please do check that also. Link of the two sum leetcode part 2 is given below
We target to cover most of the questions covered in leetcode.
So what is LeetCode :
It’s a website where people–mostly software engineers–practice their coding skills. There are 800+ questions (and growing), each with multiple solutions. Questions are ranked by level of difficulty: easy, medium, and hard.
LeetCode basically has more questions, better quality, plus a strong user base.
The primary reasons why our users LeetCode: to prepare for the technical portion of a job interview.
LeetCode and the like have risen in use because of the way interviews have evolved. Engineers believe that these resources help prepare them for what they will encounter in today’s technical aptitude screenings.
LeetCode questions are often asked during interviews at the elite tech companies: Facebook, Amazon, Apple, Netflix, and Google., some more than at others. Among the Big Five, Amazon is said to place the least emphasis on LeetCode.
LeetCode is one of the most well-known online judge platforms that you can use to practice your programming skills by solving coding questions. It has over 1,100 different problems, support for over 18 programming languages, and an active community that is always there to help you with the solutions you come up with. If your intention is to hone your coding skills, then this online judge platform is one of the best that you can use.
