335. Self Crossing
Description
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 <= 105
1 <= distance[i] <= 105
