codeforces 271A --- beautiful year

BEAUTIFUL YEAR
It seems like the year of 2013 came only yesterday. Do you know a curious fact? The year of 2013 is the first year after the old 1987 with only distinct digits.
Now you are suggested to solve the following problem: given a year number, find the minimum year number which is strictly larger than the given one and has only distinct digits.
Input
The single line contains integer y (1000 ≤ y ≤ 9000) — the year number.
Output
Print a single integer — the minimum year number that is strictly larger than y and all it's digits are distinct. It is guaranteed that the answer exists.
Examples
input
1987
output
2013
input
2013
output
2014

  1. #include <iostream>
  2. using namespace std;
  3. int iFind ( int iIn )
  4. {
  5. int iFlag; 
  6. int iBucket[10];
  7. for ( int i=0 ; i<10 ; i++ )
  8.     iBucket[i] = 0;
  9. iFlag = 0;
  10. while ( iIn )
  11.     {
  12.     if ( iBucket[iIn%10] == 0 )
  13.         iBucket[iIn%10]++; 
  14.     else
  15.         iFlag = 1;
  16.     //cout << iIn <<endl;
  17.     iIn = iIn/10;  
  18.     }  
  19. return  iFlag;
  20. }
  21. int main()
  22. {
  23. int iYear;
  24. int iTemp;
  25. cin >> iYear;
  26. while (1)
  27.     {
  28.     //cout << iYear << " ";
  29.     iYear++;   
  30.     iTemp = iFind(iYear);
  31.     if ( iTemp == 0 )
  32.         {
  33.         cout << iYear << endl;
  34.         break;

Codeforces --- string task

Petya started to attend programming lessons. On the first lesson his task was to write a simple program. The program was supposed to do the following: in the given string, consisting if uppercase and lowercase Latin letters, it: deletes all the vowels, inserts a character " . " before each consonant, replaces all uppercase consonants with corresponding lowercase ones. Vowels are letters "A", "O", "Y", "E", "U", "I", and the rest are consonants. The program's input is exactly one string, it should return the output as a single string, resulting after the program's processing the initial string. Help Petya cope with this easy task. Input The first line represents input string of Petya's program. This string only consists of uppercase and lowercase Latin letters and its length is from  1  to  100 , inclusive. Output Print the resulting string. It is guaranteed that this string is
