Notice that there are only 2 patterns of cakes possible. Like, if cake is 3x3 matrix, then possible configurations are-

RGR
GRG
RGR

and

GRG
RGR

Just find which configuration gives minimum cost.

Codechef Newbie here,

Below is my code for the recent Cookoff 89. Problem Football Match. It passes the example case, but then gives Wrong Answer after I submit. What is the error in my code?


n = int(input())
team1 = ""
team1count = 0
team2 = ""
team2count = 0
scoreArr = []
 
for x in range(n):
    testcaseNumber = int(input())
    for y in range(testcaseNumber):
        scoreArr.append(input())
    for z in scoreArr:
        if team1 != "" and team2 != "":
            continue
        elif team1 == "":
            team1 = z
            team1count = scoreArr.count(z)
        elif team2 == "":
            team2 = z
            team2count = scoreArr.count(z)
    if team1count == team2count:
        print("Draw")
    elif team1count > team2count:
        print(team1)
    else:
        print(team2)
    team1 = ""
    team2 = ""
    team1count = 0
    team2count = 0
    scoreArr = []

Thanks so much!

Consider this TC:

Expected o/p: aa
Your code gives: Draw

Where can I ask competitive programming questions?

Sometimes I am not able to understand problems or editorials or want to know some other way to solve the problem.Stack overflow community downvotes these type of questions.So is there any other site where I can post my queries and get answers in reasonable time?
