# Given a 0-indexed string word and a character ch, reverse the segment of word that starts at index 0 and ends at the index of the first occurrence of ch (inclusive). If the character ch does not exist in word, do nothing

Given a 0-indexed string `word` and a character `ch`reverse the segment of `word` that starts at index `0` and ends at the index of the first occurrence of `ch` (inclusive). If the character `ch` does not exist in `word`, do nothing.

• For example, if `word = "abcdefd"` and `ch = "d"`, then you should reverse the segment that starts at `0` and ends at `3` (inclusive). The resulting string will be `"dcbaefd"`.

Return the resulting string.Reverse Prefix of Word solution leetcode

Example 1:Given a 0-indexed string `word` and a character `ch`, reverse the segment of `word` that starts at index `0` and ends at the index of the first occurrence of `ch` (inclusive). If the character `ch` does not exist in `word`, do nothing

```Input: word = "abcdefd", ch = "d"
Output: "dcbaefd"
Explanation: The first occurrence of "d" is at index 3.
Reverse the part of word from 0 to 3 (inclusive), the resulting string is "dcbaefd".

Example 2:Given a 0-indexed string `word` and a character `ch`, reverse the segment of `word` that starts at index `0` and ends at the index of the first occurrence of `ch` (inclusive). If the character `ch` does not exist in `word`, do nothing

```Input: word = "xyxzxe", ch = "z"
Output: "zxyxxe"
Explanation: The first and only occurrence of "z" is at index 3.
Reverse the part of word from 0 to 3 (inclusive), the resulting string is "zxyxxe".
```

Example 3:Given a 0-indexed string `word` and a character `ch`, reverse the segment of `word` that starts at index `0` and ends at the index of the first occurrence of `ch` (inclusive). If the character `ch` does not exist in `word`, do nothing

[Solved] Playoff Restoration solution codeforces

```Input: word = "abcd", ch = "z"
Output: "abcd"
Explanation: "z" does not exist in word.
You should not do any reverse operation, the resulting string is "abcd".
