What does “>>>” in java mean?

Question

im trying to translate this code to python, but im having a hard time doing so, don\'t worry about the index values and variable names, I just want to know what the \">>>\" part

Answer 1

It's an "unsigned right shift".

So, if your number (x) is 11110000 (in binary).

x >>> 1 will be 01111000 (in binary).

This is opposed to x >> 1 which will result in 11111000 (in binary).

The >> tries to preserve the "sign bit" but the >>> does not.

Note: I've assumed a 8-bit integer (or a byte in Java). The same thing holds for 2-byte and 4-byte integers.
