public final class Solution821 - Shortest Distance to a Character\.
Easy
Given a string
sand a charactercthat occurs ins, return an array of integersanswerwhereanswer.length == s.lengthandanswer[i]is the distance from indexito the closest occurrence of charactercins.The distance between two indices
iandjisabs(i - j), whereabsis the absolute value function.Example 1:
Input: s = "loveleetcode", c = "e"
Output: 3,2,1,0,1,0,0,1,2,2,1,0
Explanation: The character 'e' appears at indices 3, 5, 6, and 11 (0-indexed).
The closest occurrence of 'e' for index 0 is at index 3, so the distance is abs(0 - 3) = 3.
The closest occurrence of 'e' for index 1 is at index 3, so the distance is abs(1 - 3) = 2.
For index 4, there is a tie between the 'e' at index 3 and the 'e' at index 5, but the distance is still the same: abs(4 - 3) == abs(4 - 5) = 1.
The closest occurrence of 'e' for index 8 is at index 6, so the distance is abs(8 - 6) = 2.
Example 2:
Input: s = "aaab", c = "b"
Output: 3,2,1,0
Constraints:
<code>1 <= s.length <= 10<sup>4</sup></code>
s[i]andcare lowercase English letters.It is guaranteed that
coccurs at least once ins.
