We're giving away nice huge bags containing number tiles! A bag we want to present to you contains n tiles. Each of them has a single number written on it — either 1 or 2.
However, there is one condition you must fulfill in order to receive... | instruction | 0 | 89,337 | 7 | 178,674 |

Correct Solution:
```
n = int(input())
a = [int(x) for x in input().split()]
arr = [0, 0, 0]
for item in a:
arr[item] += 1
seq = ''
if arr[1] > 2:
seq += '111'
arr[1] -= 3
elif arr[1] == 2 and arr[2]:
