Done.

Maybe it should be forked and approved again?
@KenKamau, can you please approve again, the forked one

It depends on the input string, doesn't it?

i wrote my code in c++ and i guess there is something wrong,

Random_test

Expected: equal to gvtchl znkqkh pb tcqy
Actual: gvtch lznkqk hp btcqy

No, I've copied those tests from Java test suite, if you see other thing in sample tests, click reset. These should be the sample tests:

	@Test
	public void BasicTests() {
		System.out.println("****** Basic Tests ******");
		assertEquals(3, Persist.persistence(39));
		assertEquals(0, Persist.persistence(4));
	  assertEquals(2, Persist.persistence(25));
	  assertEquals(4, Persist.persistence(999));
	}

i think you have done it in some other language this is for java:
assertEquals(4, Persist.persistence(39));
this is causing the problem

You're confusing the input of one test with the expected value of another.

    assertEquals(3, Persist.persistence(39));
    assertEquals(4, Persist.persistence(999));

Those are the assertions and you can see they're both ok.

persistence(999)==4 but it asks for 2

wait a sec
persistence(39)==3
but it is asking for 4

ok,I very sorry

In the description in Python two blocks are shown, please fix it.

Ty I thought 2 is what(in this case) we had to return.

9*9*9 = 729 (1)
7*2*9 = 126 (2)
1*2*6 = 12  (3)
1*2   = 2   (4) 

The tests are ok. This case is even explained in the kata description.
