📜  从两个范围中选择点,以使两个范围中都没有点

📅  最后修改于: 2021-05-31 22:32:18             🧑  作者: Mango

给定两个段[L1,R1][L2,R2] ,任务是从两个范围中选择两个元素xy (一个来自范围1,另一个来自范围2),使得没有元素同时属于两个范围,即x属于第一范围, y属于第二范围。如果不存在这样的元素,则打印-1

例子:

方法:

  • 如果L1!= L2R1!= R2,则这些点将是min(L1,L2)max(R1,R2)
  • 否则只能从一个范围中选择一个点,因为该范围之一完全在另一个范围内,因此我们为该点打印-1

下面是上述方法的实现:

C++
// C++ implementation of the approach
#include 
using namespace std;
 
// Function to find the required points
void findPoints(int l1, int r1, int l2, int r2)
{
 
    int x = (l1 != l2) ? min(l1, l2) : -1;
    int y = (r1 != r2) ? max(r1, r2) : -1;
    cout << x << " " << y;
}
 
// Driver code
int main()
{
    int l1 = 5, r1 = 10, l2 = 1, r2 = 7;
    findPoints(l1, r1, l2, r2);
}


Java
// Java implementation of the approach
class GFG
{
     
// Function to find the required points
static void findPoints(int l1, int r1,
                       int l2, int r2)
{
 
    int x = (l1 != l2) ? Math.min(l1, l2) : -1;
    int y = (r1 != r2) ? Math.max(r1, r2) : -1;
    System.out.println(x + " " + y);
}
 
// Driver code
public static void main(String[] args)
{
    int l1 = 5, r1 = 10, l2 = 1, r2 = 7;
    findPoints(l1, r1, l2, r2);
}
}

Python3
# Python3 implementation of the approach
 
# Function to find the required points
def findPoints(l1, r1, l2, r2):
 
    x = min(l1, l2) if(l1 != l2) else -1
    y = max(r1, r2) if(r1 != r2) else -1
    print(x, y)
 
# Driver code
if __name__ == "__main__":
     
    l1 = 5
    r1 = 10
    l2 = 1
    r2 = 7
    findPoints(l1, r1, l2, r2)

C#
// C# implementation of the approach
using System;
 
class GFG
{
    // Function to find the required points
    static void findPoints(int l1, int r1,
                            int l2, int r2)
    {
        int x = (l1 != l2) ? Math.Min(l1, l2) : -1;
        int y = (r1 != r2) ? Math.Max(r1, r2) : -1;
        Console.WriteLine(x + " " + y);
    }
     
    // Driver code
    public static void Main()
    {
        int l1 = 5, r1 = 10, l2 = 1, r2 = 7;
        findPoints(l1, r1, l2, r2);
    }
}
