Binary Prefix Divisible By 5

Easy

Given an array A of 0s and 1s, consider N_i: the i-th subarray from A[0] to A[i] interpreted as a binary number (from most-significant-bit to least-significant-bit.) Return a list of booleans answer, where answer[i] is true if and only if N_i is divisible by 5. Example 1: Input: [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: [1,1,1] Output: [false,false,false] Example 3: Input: [0,1,1,1,1,1] Output: [true,false,false,false,true,false] Example 4: Input: [1,1,1,0,1] Output: [false,false,false,false,false] Note: 1 <= A.length <= 30000 A[i] is 0 or 1
