since its introduction in java 8, the stream api has become a staple of java development. the basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. but these can also be overused and fall into some common pitfalls. to get a better understandi...
alphabetical order, or any other property that has a defined order. The efficiency of a sorting algorithm is typically measured in terms of its time complexity, which is a measure of the amount of time it takes to sort a list as a function of the...
However, the time complexity of O(n^2) in the worst and average cases makes it inefficient for large datasets. Here's the implementation of Bubble Sort Program in Java public class BubbleSort { public static void bubbleSort(int[] arr) { int n = arr.length; boolean swapped; ...

Here, we have used quicksort (inbuilt function). Sort the elements in each bucket The elements from each bucket are gathered. It is done by iterating through the bucket and inserting an individual element into the original array in each cycle. The element from the bucket is erased once ...

Time Complexity:Time complexityis a measure of the amount of time an algorithm takes to complete as a function of the size of the input. Worst Case: O(n^2) – This happens when every element in the input array needs to be switched during each run because it is in reverse order. ...
