Function prefixes_div_by5

pub fn prefixes_div_by5(a: Vec<i32>) -> Vec<bool>

1018. Binary Prefix Divisible By 5

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.

Examples

example1

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.

let a = vec![0, 1, 1];
assert_eq!(prefixes_div_by5(a), [true, false, false]);

example2

let a = vec![1, 1, 1];
assert_eq!(prefixes_div_by5(a), [false, false, false]);

example3

let a = vec![0,1,1,1,1,1];
assert_eq!(prefixes_div_by5(a), [true,false,false,false,true,false]);

example4

let a = vec![1,1,1,0,1];
assert_eq!(prefixes_div_by5(a), [false,false,false,false,false]);

1 <= A.length <= 30000 A[i] is 0 or 1
