Problem
Jennifer and Marian presented Carla with the string S.
However, Carla is not happy to receive the string S.
I wanted the string T.
The three decided to work together to change the string S to the string T.
Jennifer first sorts the letters in any order.
Marian then exchanges the lowercase letters of the two alphabets any number of times.
This operation exchanges all the same characters in the string, for example:
* aab-> Swap a and b-> bba
* aab-> Swap a and c-> ccb
Finally, Carla replaces one character with another and repeats until T.
Jennifer and Marian decided to try to reduce the number of Carla replacements.
Find the minimum number of replacements that Carla makes.
Constraints
* 1 ≤ n ≤ 105
* S and T contain only'a'~'z'
* | S | = | T | = n
Input
n
S
T
The length n of the string is given on the first line.
The character string S is given on the second line, and the character string T is given on the third line.
Output
Print the minimum number of Carla replacements on one line.

Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

We will call a string obtained by arranging the characters contained in a string a in some order, an anagram of a.
For example, `greenbin` is an anagram of `beginner`. As seen here, when the same character occurs multiple times, that character must be used that number of times.
Given are N strings s_1, s_2, \ldots, s_N. Each of these strings has a length of 10 and consists of lowercase English characters. Additionally, all of these strings are distinct. Find the number of pairs of integers i, j (1 \leq i < j \leq N) such that s_i is an anagram of s_j.
Constraints
* 2 \leq N \leq 10^5
* s_i is a string of length 10.
* Each character in s_i is a lowercase English letter.
* s_1, s_2, \ldots, s_N are all distinct.

Provide a correct Python 3 solution for this coding contest problem.
We will call a string obtained by arranging the characters contained in a string a in some order, an anagram of a.
For example, `greenbin` is an anagram of `beginner`. As seen here, when the same character occurs multiple times, that character must be used that number of times.
Given are N strings s_1, s_2, \ldots, s_N. Each of these strings has a length of 10 and consists of lowercase English characters. Additionally, all of these strings are distinct. Find the number of pairs of integers i, j (1 \leq i < j \leq N) such that s_i is an anagram of s_j.
Constraints
* 2 \leq N \leq 10^5
* s_i is a string of length 10.
* Each character in s_i is a lowercase English letter.
* s_1, s_2, \ldots, s_N are all distinct.

* c is a lowercase English letter.
Input
The input is given from Standard Input in the following format:
c
Output
If c is a vowel, print `vowel`. Otherwise, print `consonant`.
Examples
Input
a
Output
vowel
Input
z
Output
consonant
Input
s
Output
consonant
Submitted Solution:
```
c = input()
print( c in "aiueo" and "vowel" or "consonant")
``` | instruction | 0 | 104,320 | 18 | 208,640 |
Yes | output | 1 | 104,320 | 18 | 208,641 |

Provide a correct Python 3 solution for this coding contest problem.
An English booklet has been created for publicizing Aizu to the world. When you read it carefully, you found a misnomer (an error in writing) on the last name of Masayuki Hoshina, the lord of the Aizu domain. The booklet says "Hoshino" not "Hoshina".
Your task is to write a program which replace all the words "Hoshino" with "Hoshina". You can assume that the number of characters in a text is less than or equal to 1000.
Input
The input consists of several datasets. There will be the number of datasets n in the first line. There will be n lines. A line consisting of english texts will be given for each dataset.
Output
For each dataset, print the converted texts in a line.
Example
Input
3
Hoshino
Hashino
Masayuki Hoshino was the grandson of Ieyasu Tokugawa.
Output
Hoshina
Hashino
Masayuki Hoshina was the grandson of Ieyasu Tokugawa. | instruction | 0 | 105,175 | 18 | 210,350 |
"Correct Solution:
```
import re
for _ in [0]*int(input()):
print(re.sub(r"Hoshino", "Hoshina", input()))
``` | output | 1 | 105,175 | 18 | 210,351 |
