I just used to encryption to encrypt the alphabet, numbers and special characters and then binded each character to the ct array, giving us the flag.

```python
flag = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890{}_!@#$%^&*()"

a = [66128, 61158, 36912, 65196, 15611, 45292, 84119, 65338]

temp = [273896, 179019, 273896, 247527, 208558, 227481,
328334, 179019, 336714, 292819, 102108, 208558,
336714, 312723, 158973, 208700, 208700, 163266,
244215, 336714, 312723, 102108, 336714, 142107,
336714, 167446, 251565, 227481, 296857, 336714,
208558, 113681, 251565, 336714, 227481, 158973,
147400, 292819, 289507]

bitstrings = []
for c in flag:
bitstrings.append(bin(ord(c))[2:].zfill(8))

ct = []

for bits in bitstrings:
curr = 0
for i, b in enumerate(bits):
if b == "1":
curr += a[i]
ct.append(curr)

final = ""

for t in temp:
ind = ct.index(t)
final += flag[ind]

print(final)
```

Flag: `uiuctf{i_g0t_sleepy_s0_I_13f7_th3_fl4g}`
