PRPALIN wrong solution got accepted

Look at these solutions. [link1][1] [link2][2] [link3][3]

All these gives an answer 1 for input 1 which should never happen(because 1 is not a prime number). But they are given AC. This is due to weak test cases.

hoping that @admin would not just leave it aside and update the test cases.

On observing, most of the brute force solutions fall into this category.

Thank you for pointing it out so that people can take care about such mistakes in the future. However this is a very old problem and i dont think it is worth it to update test cases for such a simple test case. Just leave a comment in the comments section so people can be more careful when practicing this problem.
