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: 1 <= distance.length <= 500 1 <= distance[i] <= 500 Follow up: Could you write a one-pass algorithm with O(1) extra space?
