Explanation:
Since we are talking about binary search, let's assume that the items are sorted according to some criteria.
Time complexity of binary search is O(logN) in worst case, best case and average case as well. That means it can search for an item in Log N time where N is size of the input. Here problem talks about the item not getting found. So, this is a worst case scenario. Even in this case, binary search runs in O(logN) time.
N = 700000000.
So, number of comparisions can be log(N) = 29.3 = 29.
So, in the worst case it does comparisions 29 times
Answer:
user_age = int(input())
if user_age > 17 and user_age != 25:
print("Eligible")
else:
print("Not eligible")

Explanation:
#Using python to create the list
#first we create an empty list to store our numbers.
import math
data = []
x = 0
InputSum = 0
NumInput=int(input("how many number do you want to add"))
while x <=(NumInput):
Input=int(input("Enter the numbers here"))
data.append(Input)
x = x+1
InputSum = InputSum + Input #this is to add the numbers entered
print("The number you entered are ")
print(*data) #this print the numbers entered
print("The sum of the numbers is", InputSum)
