Question 1:
Modify the program we made in the class below, so you could convert decimal number into Hex(base 16 number):

from stack import *
def convBin(num):
    s = Stack()
    while num > 0:
        r = num % 2
        s.push(r)
        num = num // 2
    binResult = ''
    while s.isEmpty() == False:
        binResult += str(s.pop())
    return binResult

while True:
    print(convBin(int(input('Number: '))))

remember the hex number is consist of 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F

Sample Input:
Number: 1258

Sample Output:
4EA

Question 2:

We have learned infix, prefix and postfix, please write the missing prefix and postfix in the table blow:
