Very cool solution, I need to get better at ternary statements and this helps thank you.

check this if may help https://www.javatpoint.com/java-string-replaceall

No. If you initialise sum with the value 0.0 and the array is empty then your program will just return 0.0. The for used here is a for each, so if there is nothing in the array it won't do anything.

Can anyone explaine that (".", "#")? thank you very much

wow. Nice

i though with the same logic but I consumed 15 lines of code, so thanks for this xD

Wow, I did not even think of using ?: in this kata. Nice!

Think how you give change, that's your problem, the test is ok.

input number of 25 bills number of 50 bills
25 1 0
50 0 1
25 1 1
100 0 0
25 1 0
25 2 0
50 1 1
100 0 0
25 1 0
50 0 1
25 1 1
100 0 0
25 1 0
25 2 0
50 1 1
100 0 0
answer YES

Just print peopleInLine to see the inputed test.

I had problems with that test as well. Printing the input helped me realise I had misunderstood the requirement.

You are right. I missunderstood the requirement.

or the test is correct and you didn't understand the task correctly....

Test number 6 is broken in Java. It expects YES when the answer is NO
