The first line of input contains 3 integers. n a b
n: Number of gang members
a: Max weight alloted to groups
b: Number of people working together
The second line contains an array of n numbers denoting money of each member say A[i]
The third line contains an array of n numbers denoting weight of money each member has , say B[i]
The next b lines contains x and y denoting x and y work together
An integer denoting total max possible money Jacob can recieve
- 1 ≤ n ≤ 100000
- 0 ≤ a ≤ 1000
- 0 ≤ b ≤ 100000
- 0 ≤ A[i],B[i] ≤ 100000
- 1 ≤ x,y ≤ n
Input: 6 8 3 4 5 6 2 1 9 2 3 5 4 7 12 4 5 5 1 2 3 Output: 12
Here are three goups formed (1 4 5) (2 3) ( 6 ) .
From (1 4 5) : 5 is the leader & contribution from this group is 1.
From (2 3) : 2 is the leader & contribution from this group is 11.
From (6) : No contribution is possible.
Hence Total contribution is 12.
