# Help me in solving SUNDAY problem

### My code

``````# cook your dish here
T = int(input())

for i in range(T):
N = int(input())
for j in range(N):
A = list(input().split(" "))
B = [6,13,20,27,7,14,21,28]

if A in B:
C = A+B
D = list(set(C))
print(len(D))
else:

print(len(A)+len(B))

``````

The solution from my side is

``````t = int(input())

for i in range(t):
n = int(input())
fest = list(map(int,input().split()))
holidays = [6,7,13,14,20,21,27,28]
for i in range(len(fest)):
holidays.append(fest[i])
holidays = set(holidays)
print(len(holidays))
``````

Explanation for the code.

The logic is quite simple here. Since we have been given a month, we can store all the days when the holiday occurs. In the given question, these dates are 6,7,13,14,20,21,27,28 exacte as you have done). You can store it in a set or array.

After that, itâ€™s said we have N holidays which may/may not occur on Saturday or Sunday. So from this statement, you have to be on the lookout for days not in your holiday set/array.

In the end, you just have to report the size of the set or array.

Your answer seems okay to me in the first half, but I lost you at

C = A + B

Also, I am not a Python kinda guy, but your indentation seems wrong in the code you have posted here.
