Also, I just wanted to check my progress on LeetCode and took a random interview assessment where I encountered "Toeplitz Matrix" which was an easy question which am couldn't solve it. Analyze the 0/1 Knapsack Problem.

This problem is essentially let us to find whether there are several numbers in a set which are able to sum to a specific value (in this problem, the value is sum/2). Actually, this is a 0/1 knapsack problem, for each number, we can pick it or not. Let us assume dp[i][j] means whether the specific sum j can be gotten from the first i numbers.

The problem is described as follows https://leetcode.com/problems/target-sum/ You are given a list of non-negative integers, a1, a2,, an, and a target, S. Now you have 2 symbols + and -. For each integer, you should choose one from + and - as its new symbol. I first saw this problem on Leetcode — this was what prompted me to learn about, and write about, KP. This is the problem statement (reproduced partially without examples): Given a non-empty array Last Stone Weight II: A Leetcode Problem. This problem is actually 0-1 Knapsack in disguise.

Common to all versions are a set of n items, with each item 1 ≤ j ≤ n {\displaystyle 1\leq j\leq n} having an associated profit pj,weight wj. The binary decision variable xj is used to select the item. The objective is to pick some of the items, with maximal total profit, while Step3 : similary add other objects as shown in the above image till knapsack size become zero i.r m=0. Step4: When m=0 our profit will be like P=6+10+18+15+3+5* (2/3) = 55.3 (total profit). Now Even though, I have solved nearly 100 easy problems on LeetCode, I am not able to solve some easy problems in the weekly and bi-weekly contest. Also, I just wanted to check my progress on LeetCode and took a random interview assessment where I encountered "Toeplitz Matrix" which was an easy question which am couldn't solve it.
