Single-Row Keyboard
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: 4Explanation: 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 = "neetcode"
Output: 77Constraints:
keyboard.length == 26keyboardcontains each English lowercase letter exactly once in some order.1 <= word.length <= 104word[i]is an English lowercase letter.
