python code to find if an array is monotonic

Question

I'm trying to write a python code to find if an array is monotonic. Can you help me out with it? Thank you.

Answer 1

Hey Harsha, try out this code:

def monotonic(a):
    n = len(a)
    return (all(a[i]<=a[i+1] for i in range(n-1)) or
            all(a[i]>=a[i+1] for i in range(n-1)))
a = [6, 5, 4, 3, 2]
print(monotonic(a))

output:

True
