    1663 - Smallest String With A Given Numeric Value.

    Medium

    The numeric value of a lowercase character is defined as its position (1-indexed) in the alphabet, so the numeric value of a is 1, the numeric value of b is 2, the numeric value of c is 3, and so on.

    The numeric value of a string consisting of lowercase characters is defined as the sum of its characters’ numeric values. For example, the numeric value of the string "abe" is equal to 1 + 2 + 5 = 8.

    You are given two integers n and k. Return the lexicographically smallest string with length equal to n and numeric value equal to k.

    Note that a string x is lexicographically smaller than string y if x comes before y in dictionary order, that is, either x is a prefix of y, or if i is the first position such that x[i] != y[i], then x[i] comes before y[i] in alphabetic order.

    Example 1:

    Input: n = 3, k = 27

    Output: “aay”

    Explanation: The numeric value of the string is 1 + 1 + 25 = 27, and it is the smallest string with such a value and length equal to 3.

    Example 2:

    Input: n = 5, k = 73

    Output: “aaszz”

    Constraints:

    • 1 <= n <= 105
    • n <= k <= 26 * n
