We are given a bunch of binary segments. Reversing each of them, then decoding to ASCII, reveals a reversed flag.

```python
print(''.join(map(chr,[int(e[::-1],2) for e in "10111110 11100110 00101100 00110110 01100110 11111010 10011110 11001110 10000110 10100110 11111010 11001100 01101110 10010110 11100110 11111010 11001110 10100110 10010110 01001110 10000110 01110110 10010110 01000110 11111010 10011110 10101100 10000110 10100110 11011110 01001110 10000110 00100110 10000110 01001110".split(' ')])[::-1]))
