Re: 918 - ASCII Mandelbrot

The description of problem is not so clear.
Z = Z * Z + C means:
Given a complex number C = 1 + i
iteration 1: Z = 0 + C = 1 + i, d = sqrt(1 + 1) = sqrt(2);
iteration 2: Z = (1 + i) * (1 + i) + (1 + i) = 1 + 3i, d = sqrt(1 + 9) = sqrt(10);

Re: 554 - Caesar Cypher

The output specification is not so clear.
You should print a '\n' at end of EVERY line of output even the last line.
I didn't print a '\n' at last line that brings to me many WAs.

Re: 635 - Clock solitaire

The statement of problem is not so clear, I spent some time on Internet to figure out the rule of Clock game. The rule in this problem differs from regular rule. you should beware of two points below: 1. When you deal the cards, you should place four card at one clock, then four cards at two clock, ...

Re: 551 - Nesting a Bunch of Brackets

Poor problem statement.
"but if you reach the end of a test case and not find an expression not properly nested and some brackets are even opened you must print number_of_chars_of_the_case + 1"

Re: 573 - The Snail

I misunderstood the problem, the statement: "The snail has a fatigue factor of 10%, which means that on each successive day the snail climbs 10% 3 = 0.3 feet less than it did the previous day." means every day, the snail lost 10% of climbed distances, no matter climbed distances bellow zero or above...
