检查字符串是否为另一个后缀

给定两个字符串s1和s2，请检查s1是否为s2的后缀。或者简单地说，我们需要确定字符串s2是否以字符串s1结尾。
例子 ：

Input : s1 = "geeks" and s2 = "geeksforgeeks"
Output : Yes

Input : s1 = "world", s2 = "my first code is hello world"
Output : Yes

Input : s1 = "geeks" and s2 = "geeksforGeek"
Output : No

方法1(编写我们自己的代码)

C++

// CPP program to find if a string is 
// suffix of another
#include 
#include 
using namespace std;
  
bool isSuffix(string s1, string s2)
{
    int n1 = s1.length(), n2 = s2.length();
    if (n1 > n2)
      return false;
    for (int i=0; i

Java

// Java program to find if a string is 
// suffix of another
  
class GFG
{
    static boolean isSuffix(String s1, String s2)
    {
        int n1 = s1.length(), n2 = s2.length();
        if (n1 > n2)
        return false;
        for (int i=0; i

Python 3

# Python 3 program to find if a 
# string is suffix of another
def isSuffix(s1, s2):
      
    n1 = len(s1)
    n2 = len(s2)
    if (n1 > n2):
        return False
    for i in range(n1):
        if(s1[n1 - i - 1] != s2[n2 - i - 1]):
            return False
    return True
  
# Driver Code
if __name__ == "__main__":
      
    s1 = "geeks"
    s2 = "geeksforgeeks"
  
    # Test case-sensitive implementation 
    # of endsWith function
    result = isSuffix(s1, s2)
  
    if (result): 
        print("Yes")
    else:
        print( "No")

C#

// C# program to find if a string is 
// suffix of another
  
using System;
class GFG
{
    static bool isSuffix(string s1, string s2)
    {
        int n1 = s1.Length, n2 = s2.Length;
        if (n1 > n2)
        return false;
        for (int i=0; i

PHP

 $n2)
    return false;
    for ($i = 0; $i < $n1; $i++)
    if ($s1[$n1 - $i - 1] != $s2[$n2 - $i - 1])
        return false;
    return true;
}
// Driver Code
$s1 = "geeks";
$s2 = "geeksforgeeks";
  
// Test case-sensitive implementation 
// of endsWith function
$result = isSuffix($s1, $s2);
  
if ($result) 
    echo "Yes";
else
    echo "No";
  
// This code is contributed by m_kit
?>

输出：

Yes

方法2(在C++中使用boost库)
由于std :: 字符串类不提供任何endWith()函数，该函数以一个字符串结尾另一个字符串，因此我们将使用Boost库。确保包含#include boost / algorithm / 字符串.hpp和#include 字符串以正常运行代码。

C++

// CPP program to find if a string is 
// suffix of another
#include 
#include 
#include 
using namespace std;
  
int main()
{
    string s1 = "geeks", s2 = "geeksforgeeks";
  
    // Test case-sensitive implementation 
    // of endsWith function
    bool result = boost::algorithm::ends_with(s2, s1);
  
    if (result) 
        cout << "Yes";
    else
        cout << "No";
  
    return 0;
}

Java

// Java program to find if a string is 
// suffix of another
class GFG
{
  
    public static void main(String[] args) 
    {
        String s1 = "geeks", s2 = "geeksforgeeks";
  
        // Test case-sensitive implementation 
        // of endsWith function
        boolean result = s2.endsWith(s1);
  
        if (result) 
                System.out.println("Yes");
        else
            System.out.println("No");
    }
}

    s1 = "geeks";
    s2 = "geeksforgeeks";
      
    # Test case-sensitive implementation
    # of endsWith function
    result = s2.endswith(s1);
      
    if (result):
        print("Yes");
    else:
        print("No");
