[ ASSIGNMENT: ] Lambda expressions

Question

TASK :
Write the following methods that return a lambda expression performing a specified action :

1. PerformOperation isOdd() :
The lambda expression must return true
if a number is odd or false if it is even.

2. PerformOperation isPrime() :
The lambda expression must return true
if a number is prime or false if it is composite.

3. PerformOperation isPalindrome() :
The lambda expression must return true
if a number is a palindrome or false if it is not.

Sample Input :

* The first line contains an integer, N
(the number of test cases).

* The N subsequent lines each describe a test case in the form of 2 space-separated integers :
- The first integer specifies the condition to check for (1 for Odd/Even, 2 for Prime, or 3 for Palindrome).
- The second integer denotes the number to be checked.

5
1 4
2 5
3 898
1 3
2 12

Sample Output :

EVEN
PRIME
PALINDROME
ODD
COMPOSITE

HappyCodings!:)

Answer 3

Reviiea
N is the number of test cases!

For your example, you need to enter 4 cases, not 5 as you specify, then that is the wrong entry! 👍

Answer 8

What is supposed to do the integer N? 😯
What should be the output if the input is

4
1 4
2 5
3 898
1 3
2 12

Output:

"EVEN
PRIME
PALINDROME
ODD"

or

"Invalid input!"

or something else? 🤔🤔
I think it should be the first one but i'm not sure... 😅

Answer 9

Reviiea it denotes the number of lines to input as said in the assignment

Thank you both ☺️☺️

Answer 11

Максим Гвоздь yes i agree

Answer 12

Danijel Ivanović hi, i was surprised to see very few entries. i know u like detailed coding, however this was fun doing this one-liner( without using import statements on the top and with very basic error handling). i’m not bragging, but this is pure use of lambda expressions and a pure one-liner( of course someone could make a shorter version of this, i guess). it’d be cool if u check this out. thanks
