Here is a list of some of the best questions asked in interviews
https://leetcode.com/problems/two-sum/ 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] class Solution { public int[] twoSum(int[] nums, int target) { HashMap<Integer,Integer> map=new HashMap<Integer,Integer>(); for(int i=0;i<nums.length;i++){ ...
