thank you for your comment <3. i shall use string.Concat next time

Smnall notes: Second if could just be an else.. Also, take a look at string.Concat - it's Join without a delimiter

Its test cases are not written accordingy to description. It fails on case 1 of the test, where it has given 10 charachters(block walk) but its ending point is not same as starting point, as per condition the blocks walk equal to 10 and start==end, so first test case must be false irresepective of number of characters(block walk).

103 passed & 1 failed :-(

You can print them to console. See https://docs.codewars.com/training/troubleshooting/#print-input

nvm, i've solved it. But i still want to know if it's possible to see the test cases.
