iterate over the list and check if the current item and the next two items are == 1. thats a way how you find it, now you have to code it. – kai Apr 03 '14 at 11:44

Without actual code:

iterate thorough the array
count the 1s you found
if you found a 0 then start over the count
check after increasing the counter: if the counter reaches 3 then return with true
if you reached the end of the array and no more elements then return with false

Something like this, I hope I could help.
