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`
