1018 - Binary Prefix Divisible By 5.

Easy

You are given a binary array nums ( 0-indexed ).

We define xi as the number whose binary representation is the subarray nums[0..i] (from most-significant-bit to least-significant-bit).

• For example, if nums = [1,0,1], then x0 = 1, x1 = 2, and x2 = 5.

Return an array of booleans answer where answer[i] is true if xi is divisible by 5.

Example 1:

Input: nums = [0,1,1]

Output: [true,false,false]

Explanation: The input numbers in binary are 0, 01, 011; which are 0, 1, and 3 in base-10. Only the first number is divisible by 5, so answer[0] is true.

Example 2:

Input: nums = [1,1,1]

Output: [false,false,false]

Constraints:

• 1 <= nums.length <= 105
• nums[i] is either 0 or 1.
