# Day 27 of 31-Day May LeetCode Challenge

Given a set of `N`

people (numbered `1, 2, ..., N`

), we would like to split everyone into two groups of **any** size.

Each person may dislike some other people, and they should not go into the same group.

Formally, if `dislikes[i] = [a, b]`

, it means it is not allowed to put the people numbered `a`

and `b`

into the same group.

Return `true`

if and only if it is possible to split everyone into two groups in this way.
