    335 - Self Crossing\.

    Hard

    You are given an array of integers distance.

    You start at point (0,0) on an X-Y plane and you move distance[0] meters to the north, then distance[1] meters to the west, distance[2] meters to the south, distance[3] meters to the east, and so on. In other words, after each move, your direction changes counter-clockwise.

    Return true if your path crosses itself, and false if it does not.

    Example 1:

    Input: distance = 2,1,1,2

    Output: true

    Example 2:

    Input: distance = 1,2,3,4

    Output: false

    Example 3:

    Input: distance = 1,1,1,1

    Output: true

    Constraints:

    • <code>1 <= distance.length <= 10<sup>5</sup></code>

    • <code>1 <= distancei<= 10<sup>5</sup></code>
