Complexity of problems:
The practical solution of any solvable problem is complex or not is investigated by the solvability of problems. Some problems are theoretically unsolvable that means the problem has complexity which is solve by the

If we want to prove P = NP, we only need to pick up any one NPC problem and design a polynomial-time algorithm for the problem. If you want to prove P = NP, select one NPC problem based on your preference and describe your idea of a polynomial-time algorithm that solves the problem. It does not have to be a formal algorithm or pseudo-code, a description of your idea of designing such an algorithm would be fine.
If you are given a set S of integers and a number t, prove that this issue falls into the NP class. Is there a subset of S where the total number of items is t?
Note: Complexity in Data Structures and Algorithms
An NP-complete problem is a fascinating kind of problem because till now no one has discovered the
polynomial-time algorithm to solve it and also no one has proved that no polynomial-time algorithm can exist
for any NP-complete problem. It is an open research problem since it was first posed in 1971 to prove P#NP.
The NxN Queens problem can be summarized as follows: putting N chess queens on an N×N chessboard such
that none of them is able to attack any other queen using the standard chess queen's moves (row-column-
diagonal). Thus, a solution requires that no two queens share the same row, column, or diagonal. Solutions exist
only for N = 1 or N 2 4. Use the given function below to test whether a queen is attacked by another or not. You
are not allowed to use any other code to check if a queen is safe.
Implement a backtracking solution for the algorithm in Java that finds all possible solutions for N queens and
measure the execution time it takes for N=4 to 12 and compare them…
