Knapsack with Duplicate Items
Easy Accuracy: 43.9% Submissions: 1074 Points: 2

Given a set of N items, each with a weight and a value, and a weight limit W. Find the maximum value of a collection containing any of the N items any number of times so that the total weight is less than or equal to W.


Example 1:

Input: N = 2, W = 3
val[] = {1, 1}
wt[] = {2, 1}
Output: 3
Explaination: Pick the 2nd element thrice.


Example 2:

Input: N = 4, W = 8
val[] = {1, 4, 5, 7}
wt[] = {1, 3, 4, 5}
Output: 11
Explaination: The optimal choice is to 
pick the 2nd and 4th element.


Your Task:
You do not need to read input or print anything. Your task is to complete the function knapSack() which takes the values N, W and the arrays val[] and wt[] as input parameters and returns the maximum possible value.


Expected Time Complexity: O(N*W)
Expected Auxiliary Space: O(W)


1 ≤ N, W ≤ 1000
1 ≤ val[i], wt[i] ≤ 100
