    2575 - Find the Divisibility Array of a String.

    Medium

    You are given a 0-indexed string word of length n consisting of digits, and a positive integer m.

    The divisibility array div of word is an integer array of length n such that:

    • div[i] = 1 if the numeric value of word[0,...,i] is divisible by m, or
    • div[i] = 0 otherwise.

    Return the divisibility array of word.

    Example 1:

    Input: word = “998244353”, m = 3

    Output: [1,1,0,0,0,1,1,0,0]

    Explanation: There are only 4 prefixes that are divisible by 3: “9”, “99”, “998244”, and “9982443”.

    Example 2:

    Input: word = “1010”, m = 10

    Output: [0,1,0,1]

    Explanation: There are only 2 prefixes that are divisible by 10: “10”, and “1010”.

    Constraints:

    • 1 <= n <= 105
    • word.length == n
    • word consists of digits from 0 to 9
    • 1 <= m <= 109
