    Bro you and Dan Brown made it possible for me to solve this problem. Only test case 3 is always returning wrong. Can you help me? (Note: I am new to programming, sorry for any noobish mistake)

    golden = (1 + 5 ** 0.5) / 2
phi3 = golden**3
T = int(input().strip())
for i in range(T):
    N = int(input().strip())
    n = 2
    sum = 0
    while n < N:
        sum += n
        n = int(phi3 * n + 0.5)            
    print(sum)
