3106. Lexicographically Smallest String After Operations With Constraint
Medium
30 Points
String
Greedy
You are given a string s and an integer k.
Define a function distance(s1, s2) between two strings s1 and s2 of the same length n as:
For example, distance("ab", "cd") == 4, and distance("a", "z") == 1.
You can change any letter of s to any other lowercase English letter, any number of times.
Return a string denoting the lexicographically smallest string t you can get after some changes, such that distance(s, t) <= k.
Examples
Example 1
Input: s = "zbbz", k = 3
Output: "aaaz"
Explanation:
Change s to "aaaz" . The distance between "zbbz" and "aaaz" is equal to k = 3 .
Example 2
Input: s = "xaxcd", k = 4
Output: "aawcd"
Explanation:
The distance between "xaxcd" and "aawcd" is equal to k = 4.
Example 3
Input: s = "lol", k = 0
Output: "lol"
Explanation:
It's impossible to change any character as k = 0 .
Constraints
1 <= s.length <= 100
0 <= k <= 2000
s consists only of lowercase English letters.
