String - Word Counter (AMAZON-Round1)

Given a string S as input which consists of multiple words separated by a space, the program must print the count C of the words which are repeated exactly N times. The comparison of the words is case sensitive. 

Input Format: The first line contains S The second line contains N Output Format: The first line contains C

Boundary Conditions: 1 <= Length of S <= 10000 

Example Input/Output 1: 

Input: 

one two three four three two five

1

Output: 

3 

Explanation: The words which are repeated only once are one, four and five. Hence the count is 3. 

Example Input/Output 2: 

Input: 

one two three four three two five one five Three 

2 

Output: 

4

Source Code:

a,n=input().split(),int(input())

print(len(set([x for x in a if a.count(x)==n])))
