There is a special single row keyboard layout represented by a string keyboard of length $26$, indexed from $0$ to $25$. Initially, your finger is placed at index $0$. To type a character, you must move your finger to the index corresponding to that character on the keyboard. The time taken to move your finger from index $i$ to index $j$ is $|i - j|$.

Given the string keyboard and a string word, return the total time taken to type all characters of word sequentially.

Constraints:

• keyboard.length $= 26$

• keyboard contains each English lowercase letter exactly once in some order.

• $1 \leq$ word.length $\leq 10^4$

• word[i] is an English lowercase letter.
