We can represent a set of items as an X-bit integer, X is the number of items in the set. Masking a bit would mean the removal of that item from the set. For a practical application of this, be patient and read on ?. Source: giphy

WebOct 19, 2024 · Representing Sets. Bits representation of an integer are 0-indexed and the index starts from right side i.e. least significant bit. So we can represent every subset of the set {0, 1, 2, ..., n-1} as an n bit integer and whose bits indicate which element belongs to the subset. If bit at index 3 is 1 and at index 4 is 0 in binary representation of a number, then …
