每个字符连续出现后的打印频率
给定一个字符串，使得每个字符以重复的方式出现。您的任务是通过在字符串后插入每个唯一字符的频率并消除所有重复字符来打印字符串。 例:
Input : GeeeEEKKKss
Output : G1e3E2K3s2
Input : ccccOddEEE
Output : c4O1d2E3
解决上述问题的一种方法是开始一个循环，直到字符串结束，并且对于每次迭代，递增一个计数，直到第 i 个位置的字符与下面的字符匹配。 下面是对上面给定问题的实现。
C++
// CPP program to print run
// length encoding of a string
#include <iostream>
using namespace std;
void printRLE(string s)
{
for (int i = 0; s[i] != '\0'; i++) {
// Counting occurrences of s[i]
int count = 1;
while (s[i] == s[i + 1]) {
i++;
count++;
}
cout << s[i] << count << " ";
}
cout << endl;
}
// Driver code
int main()
{
printRLE("GeeeEEKKKss");
printRLE("ccccOddEEE");
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to print run
// length encoding of a string
class GFG {
static void printRLE(String s)
{
for (int i = 0; i < s.length(); i++) {
// Counting occurrences of s[i]
int count = 1;
while (i + 1 < s.length()
&& s.charAt(i)
== s.charAt(i + 1)) {
i++;
count++;
}
System.out.print(s.charAt(i)
+ "" + count + " ");
}
System.out.println();
}
// Driver code
public static void main(String args[])
{
printRLE("GeeeEEKKKss");
printRLE("ccccOddEEE");
}
}

while s[i] == s[i + 1] :

if i + 1 == len(s):
break

end = " ")
