What are graph colouring problems?

Graph colouring is a problem where we need to colour the vertices of a graph while ensuring that no two adjacent vertices have the same colour.

What is the difference between the 0-1 knapsack algorithm and the fractional knapsack?

The 0-1 Knapsack only allows you to either pick the item or not pick it. While in a functional knapsack, we can pick up even a fraction of an item until the maximum capacity is reached.

What is a kadane’s algorithm?

Kadane's algorithm helps to find the maximum sum of a contiguous subarray.

Can we solve the travelling salesman algorithm by using greedy methods?

No, you cannot use greedy methods to solve the travelling salesman problem. However, for optimization techniques, candidates can use dynamic programming to find an efficient solution.

Can we use recursion to solve the tower of Hanoi?
