2. Java 8 – Convert IntStream to Array Let us take the example to generate the first 100 odd numbers from IntStream and collect them into an array of integers. Example After creating the IntStream, we need to take the first 100 values from it usinglimit(100)function. Then use the col...

Given an array of integers, find out whether there are two distinct indices i and j in the array such that the absolute difference between nums[i] and nums[j] i...
Given an array of integers, 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements that appear twice in this array. Could you do it without extra space and in O(n) runtime?
In the given examples, we want to find the top 3 largest values in an array of Integers. 1.1.PriorityQueue PriorityQueueis anunbounded priority queue based on a priority heap. The elements of the priority queue are ordered according to their natural ordering, and theheadof this queue is the...
