Problem Statement Container With Most Water LeetCode Solution says that – You are given an integer array height of length n. There are n vertical lines are drawn such that the two endpoints of the ith line are (i, 0) and (i, height[i]). Find two lines that together with the x-axis form a container, such that the container …
Problem Statement Next Permutation LeetCode Solution – A permutation of an array of integers is an arrangement of its members into a sequence or linear order. For example, for arr = [1,2,3], the following are considered permutations of arr: [1,2,3], [1,3,2], [3,1,2], [2,3,1]. The next permutation of an array of integers is the next lexicographically greater permutation of …
Problem Statement: Camelcase Matching Leetcode Solution says that – Given an array of string “queries” and string “pattern”, return boolean array result where result[i] is true where “queries[i]” matches with “pattern”, false otherwise. A query word “queries[i]” matches with “pattern” if you can insert some lowercase English letters in “pattern” so …
Problem Statement Reverse Integer LeetCode Solution says that – Given a signed 32-bit integer x, return x with its digits reversed. If reversing x causes the value to go outside the signed 32-bit integer range [-231, 231 – 1], then return 0. Assume the environment does not allow you to store 64-bit integers (signed or unsigned). Example 1: …
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 “Iterative Preorder Traversal” states that you are given a binary tree and now you need to find the preorder traversal of the tree. We are required to find the preorder traversal using iterative method and not the recursive approach. Example 5 7 9 6 1 4 3 …
Problem Statement The problem “Print n terms of Newman-Conway Sequence” states that you are given an integer “n”. Find the first n terms of Newman-Conway Sequence then print them. Example n = 6 1 1 2 2 3 4 Explanation All the terms which are printed follow the Newman-Conway Sequence …
Suppose you have an array of integers, the problem statement asks to find out the longest bitonic subsequence. The bitonic sequence of an array is considered as the sequence which first increases and then decreases. Example arr[] = {1,4,2,76,43,78,54,32,1,56,23} 7 Explanation 1 ⇒ 4 ⇒ 76 ⇒ 78 ⇒ 54 …
Problem Statement The “Painting Fence Algorithm” states that you are given a fence having some posts (some wooden pieces or some other pieces) and some colors. Find out the number of ways to paint the fence such that at most only 2 adjacent fences have the same color. Since this …
Problem Statement The problem “Cutting a Rod” states that you are given a rod of some particular length and prices for all sizes of rods which are smaller than or equal to the input length. That is we know the price for rods of length from 1 to n, considering …
