6 postsLRU cache implementation: Here we have two methods get and set which are defined as follows: get(x) : If the key x exists in the cache, returns its value and update reference Read more →
Radix Sort is the answer when elements are in the range from 1 to n^2. The idea of Radix Sort is to do digit by digit sort starting from least significant digit Read more →
Given an array arr[ ] of N non-negative integers, the task is to sort these integers according to sum of their digits. Examples : Input : 12 10 102 31 15 Output Read more →
You are given an array of integers and sum. You have to find out if there exist a pair of sum is equal to that sum or not. Print “Yes” if exist, Read more →
Algorithm is a step-by-step procedure which is used to solve a problem. It is important Computer Science and Software Engineering. We can improve our program efficiency in cost and time by choosing Read more →
