Question

Write a function min that has two str parameters and returns the smallest. (Smallest in the sense of coming first alphabetically, not in the sense of "shortest".)

Answer 1

The function written in python is as follows

def min(str1,str2):

if str1 < str2:

return str1

else:

return str2

Explanation:

This line defines the function min, along with two parameters str1 and str2

def min(str1,str2):

This line checks if str1 is less than str2

if str1 < str2:

If yes, the function returns str1

return str1

If otherwise,

else:

The function returns str2

return str2

Take for instance

str1 = "abc"

str2 = "cba"

The function will return str1 because str1 is less than str2 in the sense that the first letter of str1 (a) is less than the first letter of str2 (c)
