# Instructions
2+
3+
Given a name and a number, your task is to produce a sentence using that name and that number as an [ordinal numeral][ordinal-numeral].
4+
Yaʻqūb expects to use numbers from 1 up to 999.
5+
6+
Rules:
7+
8+
- Numbers ending in 1 (except for 11) → `"st"`
9+
- Numbers ending in 2 (except for 12) → `"nd"`
10+
- Numbers ending in 3 (except for 13) → `"rd"`
11+
- All other numbers → `"th"`
12+
13+
Examples:
14+
15+
- `"Mary", 1` → `"Mary, you are the 1st customer we serve today. Thank you!"`
16+
- `"John", 12` → `"John, you are the 12th customer we serve today. Thank you!"`
17+
- `"Dahir", 162` → `"Dahir, you are the 162nd customer we serve today. Thank you!"`

# Introduction
2+
3+
Your friend Yaʻqūb works the counter at a deli in town, slicing, weighing, and wrapping orders for a line of hungry customers that gets longer every day.
4+
Waiting customers are starting to lose track of who is next, so he wants numbered tickets they can use to track the order in which they arrive.
5+
6+
To make the customers feel special, he does not want the ticket to have only a number on it.
7+
They shall get a proper English sentence with their name and number on it.
