What is the output of the print(x) statements in the below example? >>>x = set(("apple","banana","cherry")) >>>print(x) >>>x.add("orange") # adds a single element >>>print(x) >>>x.update(["pine apple", "mango", "grapes"]) # iterates over the sequence and adds elements in the sequence >>>print(x) output {'cherry', 'banana', 'apple'} {'cherry', 'banana', 'orange', 'apple'} {'orange', 'apple', 'pine apple', 'banana', 'grapes', 'cherry', 'mango'} Why the elements are not printed in specific order???? ANS:  set is an unordered collection of elements  set is mutable, iterable  set does not contain duplicate elements order of elements in a set is undefined

 What is the output of the following C program? #include <stdio.h> void main() { int a=25,b=4; printf("%d",(a%b)); } OUTPUT: 1 % operator gives you the remainder of an integer division.
