Examples

# Example 1

Input

values = [5,4,3,2,1], labels = [1,1,2,2,3], numWanted = 3, useLimit = 1

Output

# Example 2

Input

values = [5,4,3,2,1], labels = [1,3,3,3,2], numWanted = 3, useLimit = 2

Output

# Example 3

Input

values = [9,8,8,7,6], labels = [0,0,0,1,1], numWanted = 3, useLimit = 1

Output

Constraints

n == values.length == labels.length

1 <= n <= 2 * 104

0 <= values[i], labels[i] <= 2 * 104

1 <= numWanted, useLimit <= n
