Provide a correct Python 3 solution for this coding contest problem.
problem
Create a program that counts the number of consecutive JOI or IOI characters in a given character string. The character string consists only of uppercase letters of the alphabet. For example, the character string "JOIOIOI" in the figure below contains JOI in one place and IOI in two places.
<image>
input
The input consists of multiple datasets. Each dataset is one line and consists of uppercase letters of the alphabet of 10,000 characters or less. Input ends with EOF.
The number of datasets does not exceed 5.
output
For each dataset, output the number of JOIs found in the first line and the number of IOIs found in the second line.

E869120 found a chest which is likely to contain treasure.
However, the chest is locked. In order to open it, he needs to enter a string S consisting of lowercase English letters.
He also found a string S', which turns out to be the string S with some of its letters (possibly all or none) replaced with `?`.
One more thing he found is a sheet of paper with the following facts written on it:
* Condition 1: The string S contains a string T as a contiguous substring.
* Condition 2: S is the lexicographically smallest string among the ones that satisfy Condition 1.
Print the string S.
If such a string does not exist, print `UNRESTORABLE`.

Provide a correct Python 3 solution for this coding contest problem.
Encryption System
A programmer developed a new encryption system. However, his system has an issue that two or more distinct strings are `encrypted' to the same string.
We have a string encrypted by his system. To decode the original string, we want to enumerate all the candidates of the string before the encryption. Your mission is to write a program for this task.
The encryption is performed taking the following steps. Given a string that consists only of lowercase letters ('a' to 'z').
1. Change the first 'b' to 'a'. If there is no 'b', do nothing.
2. Change the first 'c' to 'b'. If there is no 'c', do nothing.
...
3. Change the first 'z' to 'y'. If there is no 'z', do nothing.
Input
The input consists of at most 100 datasets. Each dataset is a line containing an encrypted string. The encrypted string consists only of lowercase letters, and contains at least 1 and at most 20 characters.
The input ends with a line with a single '#' symbol.
Output
For each dataset, the number of candidates n of the string before encryption should be printed in a line first, followed by lines each containing a candidate of the string before encryption. If n does not exceed 10, print all candidates in dictionary order; otherwise, print the first five and the last five candidates in dictionary order.
Here, dictionary order is recursively defined as follows. The empty string comes the first in dictionary order. For two nonempty strings x = x1 ... xk and y = y1 ... yl, the string x precedes the string y in dictionary order if
* x1 precedes y1 in alphabetical order ('a' to 'z'), or
* x1 and y1 are the same character and x2 ... xk precedes y2 ... yl in dictionary order.

Provide a correct Python 3 solution for this coding contest problem.
Encryption System
A programmer developed a new encryption system. However, his system has an issue that two or more distinct strings are `encrypted' to the same string.
We have a string encrypted by his system. To decode the original string, we want to enumerate all the candidates of the string before the encryption. Your mission is to write a program for this task.
The encryption is performed taking the following steps. Given a string that consists only of lowercase letters ('a' to 'z').
1. Change the first 'b' to 'a'. If there is no 'b', do nothing.
2. Change the first 'c' to 'b'. If there is no 'c', do nothing.
...
3. Change the first 'z' to 'y'. If there is no 'z', do nothing.
Input
The input consists of at most 100 datasets. Each dataset is a line containing an encrypted string. The encrypted string consists only of lowercase letters, and contains at least 1 and at most 20 characters.
The input ends with a line with a single '#' symbol.
Output
For each dataset, the number of candidates n of the string before encryption should be printed in a line first, followed by lines each containing a candidate of the string before encryption. If n does not exceed 10, print all candidates in dictionary order; otherwise, print the first five and the last five candidates in dictionary order.
Here, dictionary order is recursively defined as follows. The empty string comes the first in dictionary order. For two nonempty strings x = x1 ... xk and y = y1 ... yl, the string x precedes the string y in dictionary order if
* x1 precedes y1 in alphabetical order ('a' to 'z'), or
* x1 and y1 are the same character and x2 ... xk precedes y2 ... yl in dictionary order.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Our good friend Mole is trying to code a big message. He is typing on an unusual keyboard with characters arranged in following way:
qwertyuiop
asdfghjkl;
zxcvbnm,./
Unfortunately Mole is blind, so sometimes it is problem for him to put his hands accurately. He accidentally moved both his hands with one position to the left or to the right. That means that now he presses not a button he wants, but one neighboring button (left or right, as specified in input).
We have a sequence of characters he has typed and we want to find the original message.
Input
First line of the input contains one letter describing direction of shifting ('L' or 'R' respectively for left or right).
Second line contains a sequence of characters written by Mole. The size of this sequence will be no more than 100. Sequence contains only symbols that appear on Mole's keyboard. It doesn't contain spaces as there is no space on Mole's keyboard.
It is guaranteed that even though Mole hands are moved, he is still pressing buttons on keyboard and not hitting outside it.
Output
Print a line that contains the original message.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
One day, the Grasshopper was jumping on the lawn and found a piece of paper with a string. Grasshopper became interested what is the minimum jump ability he should have in order to be able to reach the far end of the string, jumping only on vowels of the English alphabet. Jump ability is the maximum possible length of his jump.
Formally, consider that at the begginning the Grasshopper is located directly in front of the leftmost character of the string. His goal is to reach the position right after the rightmost character of the string. In one jump the Grasshopper could jump to the right any distance from 1 to the value of his jump ability.
<image> The picture corresponds to the first example.
The following letters are vowels: 'A', 'E', 'I', 'O', 'U' and 'Y'.
Input
The first line contains non-empty string consisting of capital English letters. It is guaranteed that the length of the string does not exceed 100.
Output
Print single integer a — the minimum jump ability of the Grasshopper (in the number of symbols) that is needed to overcome the given string, jumping only on vowels.

As it's the first of April, Heidi is suspecting that the news she reads today are fake, and she does not want to look silly in front of all the contestants. She knows that a newspiece is fake if it contains heidi as a subsequence. Help Heidi assess whether the given piece is true, but please be discreet about it...
Input
The first and only line of input contains a single nonempty string s of length at most 1000 composed of lowercase letters (a-z).
Output
Output YES if the string s contains heidi as a subsequence and NO otherwise.
Examples
Input
abcheaibcdi
Output
YES
Input
hiedi
Output
NO
Note
A string s contains another string p as a subsequence if it is possible to delete some characters from s and obtain p.
