Ask the user to enter a number n > = 1. there after the user will enter n-1 distinct integers between 1 and n. thus, the entered numbers contain all numbers between 1 and n except one. output the missing number. you are not allowed to use lists. you are also not allowed to use dictionaries or any programming concept more advanced that a loop. the numbers entered can be in any order.

Code below

Explanation:

n = int(input('Please enter n: '))#take input n

print('please enter the numbers')#print enter the numbers

total = 0 #intially take total as 0

original_total = 1 #intially take original_total=1

for i in range(2, n+1): #take the range 2 to n+1

total += int(input('Please enter a number: ')) # add total and enter the number

original_total += i

missing = original_total - total #you got missing number original_total - total

print('The missing number is: ' + str(missing)) # print missing number in the given data

answer(igmp);
