HALLOWEEN EVE
-----

In some other world, today is Halloween Eve.There are N trees planted in Mr. Smith’s
garden. The height of the i-th tree (1≤i≤N) is h i meters.
He decides to choose K trees from these trees and decorate them with electric lights.
To make the scenery more beautiful, the heights of the decorated trees should be as
close to each other as possible.

	

More specifically, let the height of the tallest decorated tree be hmax meters, and the
height of the shortest decorated tree be hmin meters.
The smaller the value hmax−hmin is, the better. What is the minimum possible value of
hmax−hmin?

		
		

-----Constraints-----

	    2≤K< N ≤105 

1≤hi≤109

hi is an integer
	

-----Input Format-----

Input is given from Standard Input in the following format:

N K 

h1 

h2 

: 

hN

-----Output-----

Print the minimum possible value of hmax−hmin.

		
		

-----Example Text Case-----
Input:

5 3
10
15
11
14
12

Output:

2

Explanation

If we decorate the first, third and fifth trees, hmax=12,hmin=10 so hmax−hmin=2. This is
optimal.

----- Statement -----

You need to find a string which has exactly K positions in it such that the character at that position comes alphabetically later than the character immediately after it. If there are many such strings, print the one which has the shortest length. If there is still a tie, print the string which comes the lexicographically earliest (would occur earlier in a dictionary).

-----Input-----
The first line contains the number of test cases T. Each test case contains an integer K (≤ 100).

-----Output-----
Output T lines, one for each test case, containing the required string.  Use only lower-case letters a-z.

-----Sample Input -----
2

-----Sample Output-----

Chef and his competitor Kefa own two restaurants located at a straight road. The position of Chef's restaurant is $X_1$, the position of Kefa's restaurant is $X_2$.
Chef and Kefa found out at the same time that a bottle with a secret recipe is located on the road between their restaurants. The position of the bottle is $X_3$.
The cooks immediately started to run to the bottle. Chef runs with speed $V_1$, Kefa with speed $V_2$.
Your task is to figure out who reaches the bottle first and gets the secret recipe (of course, it is possible that both cooks reach the bottle at the same time).

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first and only line of each test case contains five space-separated integers $X_1$, $X_2$, $X_3$, $V_1$ and $V_2$. 

-----Output-----
For each test case, print a single line containing the string "Chef" if Chef reaches the bottle first, "Kefa" if Kefa reaches the bottle first or "Draw" if Chef and Kefa reach the bottle at the same time (without quotes). 

-----Constraints-----
- $1 \le T \le 10^5$
- $|X_1|, |X_2|, |X_3| \le 10^5$
- $X_1 < X_3 < X_2$
- $1 \le V_1 \le 10^5$
- $1 \le V_2 \le 10^5$

-----Example Input-----
3
1 3 2 1 2
1 5 2 1 2
1 5 3 2 2

-----Example Output-----
Kefa
Chef
Draw

-----Explanation-----
Example case 1. Chef and Kefa are on the same distance from the bottle, but Kefa has speed $2$, while Chef has speed $1$.

Richik$Richik$ has just completed his engineering and has got a job in one of the firms at Sabrina$Sabrina$ which is ranked among the top seven islands in the world in terms of the pay scale. 
Since Richik$Richik$ has to travel a lot to reach the firm, the owner assigns him a number X$X$, and asks him to come to work only on the day which is a multiple of X$X$. Richik joins the firm on 1-st day but starts working from X-th day. Richik$Richik$ is paid exactly the same amount in Dollars as the day number. For example, if Richik$Richik$ has been assigned X=3$X = 3$, then he will be paid 3$3$ dollars and 6$6$ dollars on the 3rd$3rd$ and 6th$6th$ day on which he comes for work. 
On N−th$N-th$ day, the owner calls up Richik$Richik$ and asks him not to come to his firm anymore. Hence Richik$Richik$ demands his salary of all his working days together. Since it will take a lot of time to add, Richik$Richik$ asks help from people around him, let's see if you can help him out. 

-----Input:-----
- First line will contain T$T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, two integers X,N$X, N$. 

-----Output:-----
For each testcase, output in a single line which is the salary which Richik$Richik$ demands. 

-----Constraints-----
- 1≤T≤1000$1 \leq T \leq 1000$
- 1≤X<=N≤107$1 \leq X<=N \leq 10^7$

Devu has n weird friends. Its his birthday today, so they thought that this is the best occasion for testing their friendship with him. They put up conditions before Devu that they will break the friendship unless he gives them a grand party on their chosen day. Formally, ith friend will break his friendship if he does not receive a grand party on dith day.

Devu despite being as rich as Gatsby, is quite frugal and can give at most one grand party daily. Also, he wants to invite only one person in a party. So he just wonders what is the maximum number of friendships he can save. Please help Devu in this tough task !!

-----Input-----
- The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows.
- First line will contain a single integer denoting n.

- Second line will contain n space separated integers where ith integer corresponds to the day dith as given in the problem.

-----Output-----
Print a single line corresponding to the answer of the problem.

-----Constraints-----
- 1 ≤ T ≤ 104
- 1 ≤ n  ≤ 50
- 1 ≤ di ≤ 100

-----Example-----
Input:
2
2
3 2
2
1 1
Output:
2
1

-----Explanation-----
Example case 1. Devu can give party to second friend on day 2 and first friend on day 3, so he can save both his friendships.
Example case 2. Both the friends want a party on day 1, and as the Devu can not afford more than one party a day, so he can save only one of the friendships, so answer is 1.

Kabir wants to impress Tara by showing her his problem solving skills. He has decided to give the correct answer to the next question which will be asked by his Algorithms teacher.
The question asked is:
Find the sum of alternate consecutive d$d$ odd numbers from the range L$L$ to R$R$ inclusive.
if d$d$ is 3 and L$L$ is 10 and R$R$ is 34, then the odd numbers between 10 and 34 are 11,13,15,17,19,21,23,25,27,29,31,33$11,13,15,17,19,21,23,25,27,29,31,33$, and the d$d$ alternate odd numbers are 11,13,15,23,25,27$11,13,15,23,25,27$.
You are a friend of Kabir, help him solve the question.
Note:$Note:$ Number of odd number between L$L$ and R$R$ (both inclusive) is a multiple of d$d$.

-----Input:-----
- First line will contain T$T$, number of test cases.  
- First line of each test case contains one integer d$d$ . 
- Second line of each test case contains two space separated integer L$L$ and R$R$.

-----Output:-----
For each test case, print the sum modulo 1000000007.

-----Constraints:-----
- 1≤T≤106$1 \leq T \leq 10^6$
- 1≤d≤103$1 \leq d \leq 10^3$
- 1≤L<R≤106$1 \leq L < R \leq 10^6$

-----Sample Input:-----

There are n cards of different colours placed in a line, each of them can be either red, green or blue cards. Count the minimum number of cards to withdraw from the line so that no two adjacent cards have the same colour.

-----Input-----
- The first line of each input contains an integer n— the total number of cards.
- The next line of the input contains a string s, which represents the colours of the cards. We'll consider the cards in a line numbered from 1 to n from left to right. Then the $i^t$$^h$ alphabet equals "G", if the $i^t$$^h$ card is green, "R" if the card is red,  and "B", if it's blue.

-----Output-----
- Print a single integer — the answer to the problem.

-----Constraints-----
- $1 \leq n \leq 50$

-----Sample Input 1:-----
5
RGGBG

-----Sample Input 2:-----
5
RRRRR

-----Sample Input 3:-----
2
BB

-----Sample Output 1:-----
1

-----Sample Output 2:-----
4

-----Sample Output 3:-----
1

The code provided is supposed replace all the dots `.` in the specified String `str` with dashes `-`

But it's not working properly.

# Task

Fix the bug so we can all go home early.

# Notes

String `str` will never be null.
