Integers to Binary Matrix

mediumnumpy_manipulation

Implement to_binary(x, bits).

Given a 1D array x of non-negative integers, return a (len(x), bits) array of 0/1 where row i is the binary representation of x[i], most significant bit first. No for/while loops.

Constraints

no scipy, sklearn
no for/while loops

Hints

Hint 1

Build the bit masks 2**(bits-1) … 2**0, then test each value against them with broadcasting.
