Given a linked list, rearrange the node of the list as shown below: INPUT LIST: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 OUTPUT: 1 -> 8 -> 2 -> 7 -> 3 -> 6 -> 4 -> 5 INPUT LIST: 1 -> 2 -> 3 -> 4 […]

We have already seen the code to merge two sorted linked list, such that the final list is also sorted. The logic and code can be found in this post. In this post, we want to merge the two lists in a way that in the final list, element comes from the two lists alternately […]

Given an array of n integers, find the sub-array of length k with maximum sum. For example, Input Array: {6, 4, 3, 5, 1, 9, 2} k:3 Output: 15 (sum of sub-array 5, 1, 9)

Given a positive integer n, print the consecutive numbers whose sum is equal to n. For example, n = 20 Output: 2, 3, 4, 5, 6 (because 2+3+4+5+6+7 = 20) n = 29 Output: 14, 15

Given a board of size 2*n and tiles of dimension 1*2 each. In how many ways can we arrange the tiles so that entire board is covered. We can only place the tiles either horizontally or vertically without breaking them. For example, if the board is of length 3 (n=3), then tiles can be placed […]

The basic idea of DP is applicable to problems that can be thought in terms of recursion. For example, consider problem of computing n’th fibonacci term:

Consider an array that stores account numbers of all employees. One unique thing about account numbers is that they have equal number of digits. Let us take example where, account numbers are three digits long, and array has 6 account numbers are shown below int arr[ ] = {582, 675, 591, 189, 900, 770} Range […]
