Description
Given an binary array nums
and an integer k
, return true
if all 1
's are at least k
places away from each other, otherwise return false
.
Example 1:
Input: nums = [1,0,0,0,1,0,0,1], k = 2 Output: true Explanation: Each of the 1s are at least 2 places away from each other.
Example 2:
Input: nums = [1,0,0,1,0,1], k = 2 Output: false Explanation: The second 1 and third 1 are only one apart from each other.
Constraints:
1 <= nums.length <= 105
0 <= k <= nums.length
nums[i]
is0
or1
