How does this print “hello world”?

Question

I discovered this oddity:

for (long l = 4946144450195624l; l > 0; l >>= 5)
    System.out.print((char) (((l & 31 | 64) % 95) + 32));

Answer 1

You are getting a result which happens to be char representation of below values

104 -> h
101 -> e
108 -> l
108 -> l
111 -> o
32  -> (space)
119 -> w
111 -> o
114 -> r
108 -> l
100 -> d
