用给定字符串中的长度替换每个辅音序列

给定一个由小写字符组成的字符串str 。任务是用它们的长度替换连续的辅音序列。
例子：

Input: str = “abcdeiop” 
Output: a3eio1 
Given string contains 2 consonant sequences “bcd” and “p” with lengths 3 and 1.
Input: str = “abecidofu” 
Output: a1e1i1o1u 
 

方法：制作一个没有辅音的新字符串。为此，我们必须迭代给定的字符串。如果我们找到元音，它将按原样添加到新字符串中。如果我们找到辅音，那么我们必须找到完整辅音序列的长度，然后将其长度添加到新字符串中。
下面是上述方法的实现：

C++

// C++ implementation of the approach
#include 
using namespace std;
 
// Function to return the converted string
// after replacing every consonant sequence
// with its length
string replaceConsonants(string str)
{
 
    // To store the resultant string
    string res = "";
    int i = 0, count = 0;
 
    // Checking each character
    // for consonant sequence
    while (i < str.length()) {
 
        // Count the length of consonants sequence
        if (str[i] != 'a'
            && str[i] != 'e'
            && str[i] != 'i'
            && str[i] != 'o'
            && str[i] != 'u') {
            i++;
            count++;
        }
        else {
 
            // Add the length in the string
            if (count > 0)
                res += to_string(count);
 
            // Add the vowel
            res += str[i];
 
            i++;
            count = 0;
        }
    }
 
    // Check for the last consonant sequence
    // in the string
    if (count > 0)
        res += to_string(count);
 
    // Return the resultant string
    return res;
}
 
// Driver code
int main()
{
    string str = "abcdeiop";
    cout << replaceConsonants(str);
 
    return 0;
}
