Price List

You get a list of strings items and a list of integers prices. Return a list of strings with one line per item.

The price at each index belongs to the item at the same index.

A line looks like "1. apple: 3". It has the item's number, then the item, then its price.

The numbers start at 1. The lines keep the order of items.

Example 1:

Input: items = ["apple", "bread", "milk"], prices = [3, 2, 4]
Output: ["1. apple: 3", "2. bread: 2", "3. milk: 4"]
Explanation: The apple is first and costs 3.
The bread is second and costs 2.
The milk is third and costs 4.

Example 2:

Input: items = ["tea"], prices = [5]
Output: ["1. tea: 5"]
Explanation: One item gives one line, number 1.

Example 3:

Input: items = ["pen", "pen", "ink"], prices = [2, 3, 0]
Output: ["1. pen: 2", "2. pen: 3", "3. ink: 0"]
Explanation: The shop sells two kinds of pen.
Each one gets its own line, number and price.
The ink is free, so its price is 0.

Constraints:

• items and prices have the same length.
• They have 1 to 100 entries.
• Each item is one word of lowercase letters.
• Each price is a whole number from 0 to 1000.
