Hi every one cay any one please tell me whats wrong with this solution? After verifying with setter’s solutions i modified my solution which is giving AC ,i got shocked because both solutions are same in perceptive of algorithms .The difference between two solutions are in the first one using one for loop i am checking no.of correct answers and taking input of w’s , in the second solution i have separated the above logic into two different for loops , both are doing the same thing then why i got WA for first solution can one please tell me either reason or any test case where it’s failling?

I keep on getting WA and SIGSEGV on this code. Can anyone please point out what I’m doing wrong?
I am a bit new here and a little help would be greatly appreciated. I tried the below code on Turbo C++, and it worked but here it says wrong answer. Any ideas why that may be?
like everyone else: I can’t get this to work on the submission. It works on the sample data and I’ve compared to some of the completed solutions and it looks equivalent to me but I still get a WA.
T=int(input())
for t in range(0,T):
N=int(input())
ca=input()
ga=input()
count=0
winnings=[]
win=list(map(int,input().split()))
for i in range(0,len(ca)):
if ca[i]==ga[i]:
count=count+1
if count==0:
print(win[0])
else:
for i in range(1,count+1):
winnings.append(win[i])
print(max(winnings))
Whats the problem in this code? I cant find it

can any tell whats wrong withthis code
am getting correct answer in PC i gave the sample inputs getting same sample output but complilng in CodeChef showing wrong sir.please help me
Why goes it give a WA? I’m sure my solution is similar to what the editorial says.

“If K = N, there is no other option than Chef answers all the questions correctly and gets WN dollars of profit.”
for (j=0; j<1001; j++)
W[i]=0;
The above line is wrong. make it,
for (j=0; j<1001; j++)
W[j]=0;
This gives 100pts
You are not considering the case where all the answers are correct.
Your modified code :

This gives AC
Thanks for pointing it out. Really feeling bad that I missed 80 points due to that!
@prasadram126 Please change long int to long long int and then try again. The constraints of the problem are such that they need a datatype as large as long long int.
This is the link to your updated solution.

@anuragkumar33 I think you need to make arrays A and B a little bit bigger (say, 1010), because string of length N needs N + 1 byte of memory (string itself plus ‘\0’).
If cnt = n, Chef answers all questions correctly and there is no other option than Chef gets W_n dollars of profit, because he can’t leave the game when he wants. For example, for test
3
ABC
ABC
10 100 20 30
answer is 30, not 100.
