Question

Can someone revise this code, it just stops after the number is chosen. It is supposed to determine if the number is in thee array, but the program just ends.

import random

def binary_search(arr, x):
low = 0
high = len(arr) - 1
mid = 0

while low <= high:
mid = (high + low) // 2
if arr[mid] < x:
low = mid + 1
elif arr[mid] > x:
high = mid - 1
else:
return mid
return -1

arr = []
n = int(input("Enter how many elements you want in array?"))
for i in range(1,n):
arr.append(random.randint(1,100))

x = int(input("Enter which value do you seek to find from the array"))

result = binary_search(arr, x)
print("Searching for", x)

if result != -1:
print("Element is present at index", str(result))
