# 1165. Single-Row Keyboard

<https://leetcode.com/problems/single-row-keyboard>

## Description

There is a special keyboard with **all keys in a single row**.

Given a string `keyboard` of length `26` indicating the layout of the keyboard (indexed from `0` to `25`). Initially, your finger is at index `0`. To type a character, you have to move your finger to the index of the desired character. The time taken to move your finger from index `i` to index `j` is `|i - j|`.

You want to type a string `word`. Write a function to calculate how much time it takes to type it with one finger.

**Example 1:**

```
**Input:** keyboard = "abcdefghijklmnopqrstuvwxyz", word = "cba"
**Output:** 4
**Explanation:** The index moves from 0 to 2 to write 'c' then to 1 to write 'b' then to 0 again to write 'a'.
Total time = 2 + 1 + 1 = 4. 
```

**Example 2:**

```
**Input:** keyboard = "pqrstuvwxyzabcdefghijklmno", word = "leetcode"
**Output:** 73
```

**Constraints:**

* `keyboard.length == 26`
* `keyboard` contains each English lowercase letter exactly once in some order.
* `1 <= word.length <= 104`
* `word[i]` is an English lowercase letter.
