Question

Write a function in PYTHON that reads a sequence of numbers ended by 0 and prints “Sorted” if the numbers were input in increasing or decreasing order, otherwise the program must print “Not sorted” (Do not calculate 0)

Sample Input

4

3

-1

-5

0

Sample Output

Sorted

Answer 1

def isSorted():  
    a=int(input())
    b=0
    flag=0
    if a!=0:
        b=int(input())
    else:
        print('Sorted')
    if b!=0:
        if a>b:
            while b!=0:
                if a<b:
                    flag=1
                a=b
                b=int(input())
        else:
            while b!=0:
                if a>b:
                    flag=1
                a=b
                b=int(input())
    else:
        print('sorted')

    if flag!=0:
        print('Not sorted')
    else:
        print('sorted')
  
       
           

OUTPUT:

>isSorted ) 2 sorted >>isSorted () 2 sorted >>>isSorted ) 2 2 Not sorted
