Given an array of different costs(which is positive integers) of size ‘N.’ And a maximum possible jump from the current index to other index is ‘K.’ We aim to find the minimum cost to reach the end of the array. Let’s take below example to understand this problem better. In the above example, starting fromRead More »
Given an input string of size ‘N’ characters. We aim to find maximum length subsequence which is palindromic. A subsequence string is a sequence that is formed by another sequence by removing zero or more characters. Whereas a palindrome string is a string that can be read the same from the backward as forward. WeRead More »
A subsequence is a sequence formed by another sequence after removal of 0 or more items from it. The order that items appear won’t change in the subsequence. In strings, a subsequence string generates by removing 0 or more characters from the parent string. A common subsequence is a subsequence generated from two string. Let’sRead More »
We are aiming to find the total number of subsets with a given sum in an array of unsorted integers of size ‘N.’ For example, given an array {1, 2, 3, 4} and a sum of 6, the subsets with sum 6 are {1, 2, 3} and {2, 4}, making the count of subsets 2.Read More »
A thief knows all gold reserves of a neighborhood that is in a single row. Thief want’s to have a plan earlier on which houses he wants to steal. To avoid a triggering alarm his condition is to avoid stealing any two houses which are right next to each other. Let’s understand this problem withRead More »
The farmer has a knapsack with a capacity of “N” kgs, and he has products which weigh more than N kgs. He wants to fill the knapsack in such a way that he can maximize the money he can make from selling the products in the knapsack. He cannot cut the products, but he hasRead More »
Our objective is to find the number of different combinations of coin denominations that can be used to make up a given monetary amount. Given a set of coin denominations and the target amount, we aim to determine the various ways in which these coins can be arranged to reach the desired total. To betterRead More »
Fibonacci series is a series of Fibonacci numbers. A Fibonacci number is denoted as the sum of its two preceding numbers in the series. These numbers are starting from 0 and 1. Let’s see the mathematical formula for the Fibonacci number. There is an exponential number of real-world applications on the Fibonacci numbers. As perRead More »
Edit distance The minimum number of operations on a string (array of characters) to convert into another input string is called the edit distance between the two strings. The operations can be Insert a character, Remove a character, or Replace a character with another. We can solve this problem using recursion. Now let’s take aRead More »
Given an input array and a sum value as inputs and the algorithm needs to find whether there exists a subset of the input array which sums up to a given sum. Let’s try to understand the problem with some example input values. The should be a recursive solution to this problem. Let’s write aRead More »
