Here is the code for checking if array is sorted or not using recursion but one of my test cases is coming wrong, what can be the reason for this?

#1

def isSorted(arr):

  if len(arr)==1 or len(arr)==0:
	  return True
  if arr[0]<arr[1] and isSorted(arr[1:]):
	  return True
  return False

n=int(input())

arr=[int(i) for i in input().split()]

if isSorted(arr):

  print('true')

else:

  print('false')

hello @mehul.ai

use <= in place of <
