The task is to find the next greatest element for each element in an unsorted array. For each element, the program finds the nearest greater element on its right; if none exists, it assigns -1. Visual Presentation: Sample Solution: C Code: #include<stdio.h>// Function to find the next...
This method returns the first matched element in the array that satisfies a provided condition. It takes a callback function as an argument that returnstrueorfalsebased on the test condition. Thefind()method executes this callback function once for each element in the array. If the callback fu...
Since the array is increasing first & then decreasing so the maximum element would be the last one in the increasing series & the first one in the decreasing series. SO we can ignore the increasing part and check if the next element is decreasing or not. As soon as we fin...

For each element of array 1(outer loop), inner loop iterates over all elements of arr2 and check if they are equal. If element of arr1 is equal to element of arr2, then that element is pushed in array res using push() operation and we break the inner loop. After comparison of eac...
In this tutorial, Java program to find the largest number in array. Here is simple algorithm to find larget element in the array. Initialize lrg with arr[0] i.e. first element in the array. If current element is greater than lrg, then set lrg to current element. ...
2) If the input array is [0, 1, 15, 25, 6, 7, 30, 40, 50], your program should be able to find that the subarray lies between the indexes 2 and 5. Solution: 1) Find the candidate unsorted subarray a) Scan from left to right and find the first element which is greater than...

as the pivot the last element in the array. The algorithm maintains index i as it scans the array using another index j such that the elements at lo through i-1 (inclusive) are less than the pivot, and the elements at i through j (inclusive) are equal to or greater than the pivot....
Algorithm to Find Kth Smallest/Largest Element in the Array by Using the Heap A Heap is a data structure that is also a tree. The heap satifies that any parent nodes are greater/smaller than its children nodes depending on whether it is a max heap or min heap. So if we make these ...
