检查两个字符串是否包含相同顺序的相同字符

给定两个字符串s1和s2 ，任务是查找两个字符串是否包含以相同顺序出现的相同字符。例如：字符串“ Geeks”和字符串“ Geks”包含相同顺序的相同字符。
例子：

Input: s1 = “Geeks”, s2 = “Geks” 
Output: Yes
Input: s1 = “Arnab”, s2 = “Andrew” 
Output: No 
 

方法：现在有两个字符串，我们必须检查字符串是否包含相同顺序的相同字符。因此，我们将用单个元素替换连续的相似元素，即，如果我们有“ eee” ，我们将用单个“ e”替换它。现在，我们将检查两个字符串是否相等。如果相等，则打印是，否则打印否。
下面是上述方法的实现：

C++

// C++ implementation of the approach
#include 
using namespace std;
 
string getString(char x)
{
    // string class has a constructor
    // that allows us to specify size of
    // string as first parameter and character
    // to be filled in given size as second
    // parameter.
    string s(1, x);
 
    return s;
}
 
// Function that returns true if
// the given strings contain same
// characters in same order
bool solve(string s1, string s2)
{
    // Get the first character of both strings
    string a = getString(s1[0]), b = getString(s2[0]);
 
    // Now if there are adjacent similar character
    // remove that character from s1
    for (int i = 1; i < s1.length(); i++)
        if (s1[i] != s1[i - 1]) {
            a += getString(s1[i]);
        }
 
    // Now if there are adjacent similar character
    // remove that character from s2
    for (int i = 1; i < s2.length(); i++)
        if (s2[i] != s2[i - 1]) {
            b += getString(s2[i]);
        }
 
    // If both the strings are equal
    // then return true
    if (a == b)
        return true;
 
    return false;
}
 
// Driver code
int main()
{
    string s1 = "Geeks", s2 = "Geks";
 
    if (solve(s1, s2))
        cout << "Yes";
    else
        cout << "No";
 
    return 0;
}

    String s = String.valueOf(x);
    return s;
}
 
// Function that returns true if
