Function FindKthMax

math/kthnumber.go:11–14

FindKthMax returns the kth large element given an integer slice with nil `error` if found and returns -1 with `error` `search.ErrNotFound` if not found. NOTE: The `nums` slice gets mutated in the process.

(nums []int, k int)

// with nil `error` if found and returns -1 with `error` `search.ErrNotFound`
// if not found. NOTE: The `nums` slice gets mutated in the process.
func FindKthMax(nums []int, k int) (int, error) {
	index := len(nums) - k
	return kthNumber(nums, index)
}

// FindKthMin returns kth small element given an integer slice
// with nil `error` if found and returns -1 with `error` `search.ErrNotFound`
