# Instructions
2+
3+
Given a name and a number, your task is to produce a sentence with an [ordinal numeral][ordinal-numeral] to print onto the ticket.
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 not ending in 1, 2, or 3 → `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+
He sees that waiting customers start to loose track of who is next, so he wants to have numbered tickets for them to pick when they arrive.
5+
6+
He is a nice person, and so he does not want to have only a number on the ticket. They shall get a proper English sentence with their name and number in it.
