Given n items with size \[Ai\] and value Vi, and a backpack with size m. What's the maximum value can you put into the backpack?
Given n items with size \(A_i\), an integer m denotes the size of a backpack. How full you can fill this backpack?
Write an efficient algorithm that searches for a value in an m x n matrix.
This matrix has the following properties:
- Integers in each row are sorted from left to right.
- The first integer of each row is greater than the last integer of the previous row.
Implement
int sqrt(int x)
.Compute and return the square root of x.
