Question: 
Write a python function to calculate the number of odd days in a given year.


Model's Code:
def odd_Days(year):
    days = year * 365 + year // 4 - year // 100 + year // 400
    return days % 7



Sample Correct Code:
def odd_Days(N): 
    hund1 = N // 100
    hund4 = N // 400
    leap = N >> 2
    ordd = N - leap 
    if (hund1): 
        ordd += hund1 
        leap -= hund1 
    if (hund4): 
        ordd -= hund4 
        leap += hund4 
    days = ordd + leap * 2
    odd = days % 7
    return odd 


Asserts:
assert odd_Days(100) == 5
assert odd_Days(50) ==6
assert odd_Days(75) == 2
