29 바이트 골프 를 한 Kevin Cruijssen 에게 감사 합니다.
언 골프 버전 :
n -> { // lambda taking an int as argument
var c = new char[++n][n]; // the output; increment the virality since the root does not count
for(var d : c) // for every line
java.util.Arrays.fill(d,' '); // initialize it with spaces
for(int i = 0, j = 0, // coordinates of the first branch
k = 0, l = 0, // coordinates of the second branch
r = 0, s = 0, // offsets for the first branch, one will be 0 and the other 1 always except for the first '*' where the two branches overlap
t = 0, u = 0; // offsets for the second branch, one will be 0 and the other 1 always except for the first '*' where the two branches overlap
n-- > 0; ) { // decrement virality and repeat as many times
c[i+=r][j+=s] = c[k+=t][l+=u] = 42; // move according to offsets and place an '*' for each branch, 42 is ASCII code
