Problem: Problem Description

You are building a text analyzer tool. One of its features is detecting vowel clusters in a word.

Your task is to write a program that takes a word and counts how many vowel clusters it contains.

What is a Vowel Cluster?

A vowel cluster is a group of one or more vowels (a, e, i, o, u) that appear consecutively without any consonants in between.

Examples:

- "ae" is one vowel cluster.  
- "a" is one vowel cluster.  
- "abc" has one vowel cluster: "a".  

For example, in the word "beautiful", the vowels "eau" form one vowel cluster. Later, "i" and "u" form their own clusters. Hence, the word contains 3 vowel clusters in total.

--------------------------------------------------

Input Format

- An integer n, the length of the word.  
- A word of n lowercase English letters.

--------------------------------------------------

Output Format

- Print a single integer representing the number of vowel clusters in the word.

--------------------------------------------------

Assumptions on Input

1 <= n <= 100000  

--------------------------------------------------

Note

- Do not print any extra messages such as:
  cout << "Enter a number"
  cout << "The computed answer is"
- Use cout only to print the computed final output.
- Do not print unnecessary spaces.
- Do not hard-code the result.
- If any test case passes by simply printing output without logic, marks will not be awarded.

Problem: Write a C++ program that takes a positive integer as input from the user and determines whether or not it is a palindrome. The program should print 1 if the number is a palindrome, otherwise print 0. The input number should be greater than 0 and should not begin with 0. The program should not use arrays.

Student submission:
#include<iostream>

using namespace std;
int main(){
int n,i,d=0;
cin>>n;
i=n;
while(i>0){
   int rem=i%10;
   d=d*10+rem;
   i/=10;
   }
 if(n==d) cout<<"1";
 else cout<<"0";
 }
