CodeChef Problem : Recent contest problems - Difficulty Rating:793

 

CodeChef  Problem  -  Difficulty Rating:793

Input Format

• First line will contain $�$, number of test cases. Then the test cases follow.
• Each test case contains of two lines of input.
• First line of input contains the total count of problems that appeared in the two recent contests - $�$.
• Second line of input contains the list of $�$ contest codes. Each code is either START38 or LTIME108, to which each problem belongs.

Output Format

For each test case, output two integers in a single new line - the first integer should be the number of problems in START38, and the second integer should be the number of problems in LTIME108.

Constraints

• $1\le �\le 10$
• $1\le �\le 1000$
• Each of the contest codes will be either START38 or LTIME108.

Explanation:

Test case $1$: There are $2$ START38s in the input, which means that there were $2$ problems in START38. Similarly, there was $1$ problem in LTIME108.

Test case $2$: There is $1$ START38 in the input, which means that there was $1$ problem in START38. Similarly, there were $3$ problems in LTIME108.

Test case $3$: There are no START38s in the input, which means that were $0$ problems in START38. Similarly, there were $2$ problems in LTIME108.

Test case $4$: There are $2$ START38s in the input, which means that there were $2$ problems in START38. Similarly, there were $4$ problems in LTIME108.

Solution:

def count_problems_in_contests(test_cases):

  for i in test_cases:

    start38_count = i.count('START38')

    ltime108_count = i.count('LTIME108')

    

    print(start38_count, ltime108_count)

if __name__ == "__main__":

    T = int(input())

    test_cases = []

    for _ in range(T):

        N = int(input())

        contest_codes = input().split()

        test_cases.append(contest_codes)

    count_problems_in_contests(test_cases)
