{ "data": { "question": { "questionId": "1782", "questionFrontendId": "1663", "boundTopicId": null, "title": "Smallest String With A Given Numeric Value", "titleSlug": "smallest-string-with-a-given-numeric-value", "content": "
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.
\n
Example 1:
\n\n\nInput: n = 3, k = 27\nOutput: "aay"\nExplanation: 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.\n\n\n
Example 2:
\n\n\nInput: n = 5, k = 73\nOutput: "aaszz"\n\n\n
\n
Constraints:
\n\n1 <= n <= 105
n <= k <= 26 * n
