Custom Comparators are used to compare the members or objects of user-defined containers (class/data structure).
Starting with a 1-indexed array of zeros and a list of operations, for each operation add a value to each the array element between two given indices, inclusive. Once all operations have been performed, return the maximum value in the array.
The Heapsort algorithm uses Heap data structure to sort an array in O(nlogn) time complexity. It starts by calling Build-Max-Heap.
A sorting algorithm is an algorithm that puts elements of a list into an order. Most frequently we’re required to sort data structures such as arrays, linked lists etc having numerical values. There’re various algorithms to sort a container or a data structure. In this post, we’ll discuss most popular or […]
Quicksort is a sorting algorithm whose worst-case running time is O(n^2), for an input of size n. Quicksort, in spite of having worse time complexity than Merge Sort which is O(nlogn), it is a better practical choice for sorting. This is because it is remarkably efficiently on average cases, where its […]
Sorting means arranging a set of data in an order. There’re various algorithms to sort the data (in a data structure) in increasing or decreasing order. These algorithms can be divided on basis of various factors: Inplace sorting means that all the data which is to be sorted can be accommodated […]
Quicksort algorithm was developed by a British computer scientist Tony Hoare in 1959. “Quick Sort” is capable of sorting a list of data elements significantly faster (twice or thrice faster) than any of the common sorting algorithms and that’s why it is the favourite topic of interviewers in programming interviews. It is one […]
