Introduction

Given a number N, the task is to find whether there is consecutive 0’s on converting it to base B.

Program

def find(ip_num, ip_base):
    base = convert(ip_num, ip_base)
    if (verify(base)):
        print("Consecutive 0 exists!")
    else:
        print("Consecutive 0 does not exists!")


def convert(ip_num, ip_base):


    x = 1
    y = 0
    while (ip_num != 0):
# Convert ip_num into given base
        temp = ip_num % ip_base
        ip_num = ip_num//ip_base
        y = temp * x + y
        x *= 10
    return y


def verify(ip_num):


    temp = False
    while (ip_num != 0):
        temp1 = ip_num % 10
        ip_num = ip_num // 10
# Check consecutive 0
        if (temp == True and temp1 == 0):
            return False
        if (temp1 > 0):
            temp = False
            continue
        temp = True
    return True


ip_num = int(input("Enter the number: "))
ip_base = int(input("Enter the base: "))
find(ip_num, ip_base)

Output

Explanation

In the above program, we have created the function convert() and verify() to convert the number to base B and verify whether consecutive 0 exists. If the condition satisfies, the statement “Consecutive 0 exists!” is printed otherwise “Consecutive 0 does not exists!” is printed on the screen.
