Doubt regarding a question in practice section

In beginners section’s practice questions
There’s a question named IPL and RCB
I solved that question in python 3.6 and it was running correctly for the sample input and tried to submit my code
but it is generating error
Please find the error
this is my code
please tell me where am I going wrong?
t=int(input())
while(t!=0): # x=points required and y=matches left and in output , print min matches to win
x,y=map(int,input().split(" "))
if x==2y:
print(y)
elif x==1 and y!=0:
print(0)
elif x%2!=0 and x!=1 and x<2
y:
print(x//2)
else:
print(x/2)
t-=1
