Count Divisors (Hackerearth)

You have been given 3 integers - l, r and k. Find how many numbers between l and r (both inclusive) are divisible by k. You do not need to print these numbers, you just have to find their count.

Input Format
The first and only line of input contains 3 space separated integers l, r and k.

Output Format
Print the required answer on a single line.

Constraints
1≤l≤r≤1000
1≤k≤1000

SAMPLE INPUT
 
1 10 1
SAMPLE OUTPUT
 
10
SOLUTION:
l,r,k = map(int,input().split())
c=0
for i in range(l,r+1):
    if i%k==0:
        c+=1
print(c)

Sort in specific order (GFG)

  Given an array   A   of positive integers. Your task is to sort them in such a way that the first part of the array contains odd numbers sorted in descending order, rest portion contains even numbers sorted in ascending order. Input: The first line of input contains an integer  T  denoting the number of test cases. Then  T  test cases follow. Each test case contains an integer  N  denoting the size of the array. The next line contains  N  space separated values of the array. Output: For each test case in a new line print the space separated values of the modified array. Constraints: 1 <= T <= 10 3 1 <= N <= 10 7 0 <= A i  <= 10 18 Example: Input: 2 7 1 2 3 5 4 7 10 7 0 4 5 3 7 2 1 Output: 7 5 3 1 2 4 10 7 5 3 1 0 2 4 Explanation: Testcase1:  Array elements 7 5 3 1 are odd and sorted in descending order, whereas 2 4 10 are even numbers and sorte...

Chef and Remissness Problem Code: REMISS (CodeChef)

Chef is now a corporate person. He has to attend office regularly. But chef does not want to go to office, rather he wants to stay home and discover different recipes and cook them. In the office where chef works, has two guards who count how many times a person enters into the office building. Though the duty of a guard is 24 hour in a day, but sometimes they fall asleep during their duty and could not track the entry of a person in the office building. But one better thing is that they never fall asleep at the same time. At least one of them remains awake and counts who enters into the office. Now boss of Chef wants to calculate how many times Chef has entered into the building. He asked to the guard and they give him two integers  A  and  B , count of first guard and second guard respectively. Help the boss to count the minimum and maximum number of times Chef could have entered into the office building. Input The first line of the input contains an integer  T ...
