给定一个字符串 s ，打印字符串的反串，并从反串中删除原字符串中有元音的字符。 例:
input : geeksforgeeks
output : segrfseg
explanation :
reversed string is skeegrofskeeg, removing characters
from indexes 1, 2, 6, 9 & 10 (0 based indexing),
we get segrfseg .
input :duck
output :kud
一个简单的解决方法就是先倒串，然后遍历倒串，去掉元音。 一个高效的pg电子试玩链接的解决方案是在一次遍历中完成两个任务。 创建一个空字符串 r，遍历原始字符串 s，并将值赋给字符串 r。检查在该索引处，原始字符串是否包含辅音。如果是，则打印字符串 r 索引处的元素 上述方法的基本实现:
c
// cpp program for removing characters
// from reversed string where vowels are
// present in original string
#include
using namespace std;
// function for replacing the string
void replaceoriginal(string s, int n)
{
// initialize a string of length n
string r(n, ' ');
// traverse through all characters of string
for (int i = 0; i < n; i ) {
// assign the value to string r
// from last index of string s
r[i] = s[n - 1 - i];
// if s[i] is a consonant then
// print r[i]
if (s[i] != 'a' && s[i] != 'e' && s[i] != 'i'
&& s[i] != 'o' && s[i] != 'u') {
cout << r[i];
}
}
cout << endl;
}
// driver function
int main()
{
string s = "geeksforgeeks";
int n = s.length();
replaceoriginal(s, n);
return 0;
}
