A linked list is a data structure that stores data elements in linked form. Each node of the linked list has a data element and a link.Print reverse of a linked list is a common problem that needs to be addressed in problem solving. So, here we will learn an interesting way to print reverse of a linked list in c++ programming language.Generally print a reverse linked list needs modifications in the list or multiple traversing of the list but this method does not require any such things and also traverses the linked list only once.The logic of this method ...

What is the time complexity of insertion sort?Time complexity is the amount of time taken by a set of codes or algorithms to process or run as a function of the amount of input.For insertion sort, the time complexity is of the order O(n) i.e. big O of n in best case scenario. And in the average or worst case scenario the complexity is of the order O(n2).What will be the time complexity of sorting when insertion sort algorithm is applied to n sized array of the following form: 6, 5, 8, 7, 10, 9 …… I, i-1The time complexity ...

Amortized analysis for a sequence of operations is used to determine the run time, the average time required by the sequence. In cannot be treated as an average-case analysis done on the algorithm as it does not always take the average case scenario. There are cases that occur as a worst-case scenario of analysis. So, amortized analysis can be treated as a worst-case analysis for multiple operations in a sequence. Here, the cost of doing each operations in different and for some its high. This problem is a general view using the binary counter.Let’s see the working and implementation in ... Read More

Problem statementN participants of the competition were split into M teams in some manner so that each team has at least one participant. After the competition each pair of participants from the same team became friends.Your task is to write a program that will find the minimum and the maximum number of pairs of friends that could have formed by the end of the competition.Algorithm1. We can obtain max pairs using below formula: maxPairs = ((n – m) * (n – m + 1)) / 2 2. We can obtain min pairs using below formula: minPairs = m * (((n ... Read More
DescriptionGiven an array of size, N. Find an element X such that the sum of array elements should be minimum when XOR operation is performed with X and each element of an array.If input array is: arr [] = {8, 5, 7, 6, 9} then minimum sum will be 30 Binary representation of array elments are: 8 : 1000 5 : 0101 7 : 0111 6 : 0101 9 : 1001 If X = 5 then after performing XOR sum will be 30: 8 ^ 5 = 13 5 ^ 5 = 0 7 ^ 5 = 2 6 ^ ...
