Write a program to count number of ways to calculate a target number from elements of specified array by using only addition and subtraction operator. The use of any other operator is forbidden.
In Pots of gold game, there are two players A & B and pots of gold arranged in a line, each containing some gold coins. The players can see how many coins are there in each gold pot and each player
Given a string, find minimum cuts needed to partition it such that each partition is a palindrome.
Given a square matrix, print maximum length snake sequence in it. A Snake sequence is defined as a sequence of numbers where each new number, which can only be located to the right or down of the current number, is either plus or minus one.
3-partition problem: Given a set S of positive integers, determine if it can be partitioned into three disjoint subsets that all have same sum and they cover S.
Given a string and a dictionary of words, determine if string can be segmented into a space-separated sequence of one or more dictionary words.
Given a linear equation of k variables, count total number of possible solutions of it.
The longest decreasing subsequence problem is to find a subsequence of a given sequence in which the subsequence’s elements are in sorted order, highest to lowest, and in which the subsequence is as long as possible.
Given three strings, return true if third string is interleaving of first and second string. i.e., it is formed from all characters of first and second string and order of characters is preserved.
Implement your own diff utility. i.e given two similar strings, efficiently list out all differences between them.
A string is K-Palindrome if it becomes a palindrome on removing at most k characters from it. Write an algorithm to check if a given string is K-Palindrome or not.
