Let’s have a look at this line: int a = Math.round((float)(360/size)); And assume that size==361. Since size is an int we have an integer-division and 360/size equals 0. Then you cast it to a float resulting in 0.0f, round it (givin 0.0f) and assign it to an int that’s also 0 as a result. What … Read more

What you can do is: If Creation fails pass back a bool and try again from scratch. public void Generate() { Fill(); while(!Fleet()) { // I assume Fill clears your board again?! Fill(); } } public bool Fleet() { return Ship2(Utility.R(1,9),Utility.R(1,9),Utility.R(4)) && Ship3(Utility.R(1,9),Utility.R(1,9),Utility.R(4)) && Ship3(Utility.R(1,9),Utility.R(1,9),Utility.R(4)) && Ship4(Utility.R(1,9),Utility.R(1,9),Utility.R(4)) && Ship5(Utility.R(1,9),Utility.R(1,9),Utility.R(4)); } public bool Ship2(int x, int … Read more

Let’s call PP your Potential Prime. (1) Choose a random number a less than PP. (2) Calculate a^(p-1)/2 mod PP. (3) If a^(PP-1)/2 /= 1 or -1 (mod PP), then PP is not prime. (4) If a^(PP-1)/2 = 1 or -1 (mod PP), then the probability that PP is not prime is less than 50%. … Read more
I wouldn’t use a regex here, I’d just remove the two quotes (replacing ” with nothing using str_replace()), then split the string into words (using explode() with ‘ ‘ as the delimiter), then grab the last “word” using array_pop(). url=”abc123.php”; $data = file_get_contents($url); //$data contains “N/A – -0.09%” (the string to parse) $match = array_pop(explode(‘ … Read more
