Missing number in array from 1 to 100 - Python

Q#1

I found another interest interview question on some blog... (https://simpleprogrammer.com/programming-interview-questions/)

So, I decide to solve these question one by one by python

Question 1:

        How do you find the missing number in a given integer array of 1 to 100?

We need input from user for array. But don't worry about it. Here Python code also do it for us randomly in every time.

Let's Code and Check...

CODE:

import random

a = []

while len(a) < 90:

  ranAdd = random.randint(1,100)

  if ranAdd in a:

    pass

  else:

    a.append(ranAdd)

  

a.sort()

print(a)

missnum = []

for i in range(1,101):

  if i in a:

    pass

  else:

    missnum.append(i)

    

print(missnum)
