Question for you all

Any input would be greatly appreciated. I am wondering why I am getting this answer wrong. I identified the patterns and found that even positions decrease as the series goes on and the odd positions decrease. I built a loop to make make a new string that stores the reversing of the numbers. Then I only look for the index of the string containing k.

When I text it with the example zero it works. I have also done it with other manual examples and it seems to work fine. Not sure why it marks every other example as incorrect ` if name == 'main': t = int(input().strip()) for _ in range(t): # Loop t times first_multiple_input = input().rstrip().split()

    n = int(first_multiple_input[0])

    k = int(first_multiple_input[1])
    result_string = ""
    high = n - 1
    low = 0
    for i in range(n):
        if i % 2 == 0:  # Even index: use the high value
            result_string += str(high)
            high -= 1
        else:  # Odd index: use the low value
            result_string += str(low)
            low += 1

    index = result_string.index(str(k))  # Find the index of K as a string
    print(index)    

Is this broken? The Solution code only brings in the first test case. The T variable tells me there should be 2 cases but only one value for N and K come in. Is there something I need to do to get all the test cases?

The Reverse Game challenge on HackerRank is such a fun puzzle to work through! I love how it really pushes you to think about the problem from a different angle and optimize your approach. Sometimes these logic-based challenges remind me of how different types of games can make you think strategically, even when you're just playing for fun. I’ve found apps like https://aviator-pinup.info/best-aviator-game-app do a great job of blending simple gameplay with a need for quick thinking, which is a cool way to keep the brain sharp when you need a break from coding but still want to stay engaged!
