You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 786. K-th Smallest Prime Fraction.go
    path of file: ./repos/LeetCode-Go/leetcode/0786.K-th-Smallest-Prime-Fraction
    
    the code of the file until where you have to start completion: package leetcode

import (
	"sort"
)

// 解法一 二分搜索
func kthSmallestPrimeFraction(A []int, K int) []int {
	low, high, n := 0.0, 1.0, len(A)
	// 因为是在小数内使用二分查找，无法像在整数范围内那样通过 mid+1 和边界判断来终止循环
	// 所以此处根据 count 来结束循环
	for {
		mid, count, p, q, j := (high+low)/2.0, 0, 0, 1, 0
		for i := 0; i < n; i++ {
		
    
func kthSmallestPrimeFraction1(A []int, K int) []int {
	if len(A) == 0 || (len(A)*(len(A)-1))/2 < K {
		return []int{}
	}
	fractions := []Fraction{}
	for i := 0; i < len(A); i++ {
		for j := i + 1; j < len(A); j++ {
			fractions = append(fractions, Fraction{molecule: A[i], denominator: A[j]})
		}
	}
	sort.Sort(SortByFraction(fractions))
	return []int{fractions[K-1].molecule, fractions[K-1].denominator}
}
