The problem “Longest Repeated Subsequence” states that you are given a string as an input. Find out the longest repeated subsequence, that is the subsequence that exists twice in the string. Example aeafbdfdg 3 (afd) Approach The problem asks us to find out the longest repeated subsequence in the string. …
The problem “Sequences of given length where every element is more than or equal to twice of previous” provides us with two integers m and n. Here m is the largest number that can exist in the sequence and n is the number of elements that must be present in the …
The problem “Find maximum length Snake sequence” states that we are provided with a grid containing integers. The task is to find a snake sequence with the maximum length. A sequence having adjacent numbers in the grid with an absolute difference of 1, is known as a Snake sequence. Adjacent …
The problem “Minimum sum of multiplications of n numbers” states that you are given n integers and you need to minimize the sum of multiplication of all the numbers by taking two elements that are adjacent at a time and putting back their sum mod 100 until a single number …
The problem “Count ways to reach the nth stair using step 1, 2, or 3” states that you are standing on the ground. Now you need to reach the end of the staircase. So how many ways are there to reach the end if you can jump only 1, 2, …
Problem Statement The problem “Minimum Sum Path in a Triangle” states that you are given a sequence in the form of a triangle of integers. Now starting from the top row what is the minimum sum you can achieve when you reach the bottom row? Example 1 2 3 5 …
The problem “Count even length binary sequences with same sum of first and second half bits” states that you are given an integer. Now find out the number of ways to construct a binary sequence of size 2*n such that the first half and second half have the same number …
The problem “Longest subsequence such that difference between adjacents is one” states that you are given an integer array. Now you need to find the length of longest subsequence such that the difference of adjacent elements is 1. Example 1 2 3 4 7 5 9 4 6 Explanation As …
Problem Statement The problem “Maximum path sum in a triangle” states that you are given some integers. These integers are arranged in the form of a triangle. You are starting from the top of the triangle and need to reach the bottom row. For doing this, you move to the …
Problem Statement The problem “Path with maximum average value” states that you are given a 2D array or a matrix of integers. Now consider you are standing at the top-left cell and need to reach the bottom right. For reaching the destination, you need to move along either in the …
