Hello friends can someone tell me how to approach this problem ? I am getting WA.

Here is my latest submission. If it’s too messy, here is the approach I used :

```
for __ in range(readInt()):
n = readInt()
arr = readInts()
brr = readInts()
last,f,count = -1,1,0
for i in range(n):
if arr[i]==1 and last==-1:
last = brr[i]
elif arr[i]==1:
if last<=brr[i]:
last = brr[i]
else:
count+=1
if count>1:
f = 0
break
if f:
print "#laughing_arjun"
else:
print "#itsnot_arjun"
```
