检查给定四个整数(或边)是否构成矩形
给定四个正整数，确定矩形的边长是否为 a、b、c 和 d(任意顺序)。 例:
Input : 1 1 2 2
Output : Yes
Input : 1 2 3 4
Output : No
方法 1 :- 我们将检查两个整数中是否有任何一个是相等的，并使用几个 if else 条件确保其余两个也是相等的。
C++
// A simple program to find if given 4
// values can represent 4 sides of rectangle
#include <iostream>
using namespace std;
// Function to check if the given
// integers value make a rectangle
bool isRectangle(int a, int b, int c, int d)
{
// Square is also a rectangle
if (a == b == c == d)
return true;
else if (a == b && c == d)
return true;
else if (a == d && c == b)
return true;
else if (a == c && d == b)
return true;
else
return false;
}
// Driver code
int main()
{
int a, b, c, d;
a = 1, b = 2, c = 3, d = 4;
if (isRectangle(a, b, c, d))
cout << "Yes";
else
cout << "No";
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// A simple program to find if
// given 4 values can represent
// 4 sides of rectangle
class GFG {
// Function to check if the given
// integers value make a rectangle
static boolean isRectangle(int a, int b,
int c, int d)
{
// Square is also a rectangle
if (a == b && a == c &&
a == d && c == d &&
b == c && b == d)
return true;
else if (a == b && c == d)
return true;
else if (a == d && c == b)
return true;
else if (a == c && d == b)
return true;
else
return false;
}
// Driver code
public static void main(String[] args)
{
int a = 1, b = 2, c = 3, d = 4;
if (isRectangle(a, b, c, d))
System.out.println("Yes");
else
System.out.println("No");
}
}
