How to solve recursion by brute force?

Method 1: Recursion by Brute-Force algorithm OR Exhaustive Search. Approach: A simple solution is to consider all subsets of items and calculate the total weight and value of all subsets. Consider the only subsets whose total weight is smaller than W.

What is the proper fraction value for 1/10?

In this case the whole number value is empty and the proper fraction value is 1/10. Can all decimals be converted into a fraction? Not all decimals can be converted into a fraction.

What does 1=1 mean in SQL Server?

With the 1=1 at the start, the initial and has something to associate with. I've never seen this used for any kind of injection protection, as you say it doesn't seem like it would help much. I have seen it used as an implementation convenience. The SQL query engine will end up ignoring the 1=1 so it should have no performance impact.

How do you find the maximum value of a subset?

Approach: A simple solution is to consider all subsets of items and calculate the total weight and value of all subsets. Consider the only subsets whose total weight is smaller than W. From all such subsets, pick the maximum value subset. Optimal Sub-structure: To consider all subsets of items, there can be two cases for every item.
