In JavaScript, ```if..else``` is the most basic condition statement,
it consists of three parts:```condition, statement1, statement2```, like this:
```python
if condition: statementa
else:         statementb
```
It means that if the condition is true, then execute the statementa, otherwise execute the statementb.If the statementa or statementb more than one line, you need to add ```{``` and ```}``` at the head and tail of statement in JS, to keep the same indentation on Python and to put a `end` in Ruby where it indeed ends.

An example, if we want to judge whether a number is odd or even, we can write code like this:
```python
def odd_even(n):
    if n%2: return "odd number"
    else:   return "even number"
```

If there is more than one condition to judge, we can use the compound if...else statement. an example:
```python
def old_young(age):
    if age<16:        return "children"
    elif (age<50): return "young man" #use "else if" if needed
    else:             return "old man"
```
This function returns a different value depending on the parameter age.

Looks very complicated? Well, JS and Ruby also support the ```ternary operator``` and Python has something similar too:
```python
statementa if condition else statementb
```
Condition and statement separated by "?", different statement separated by ":" in both Ruby and JS; in Python you put the condition in the middle of two alternatives.
The two examples above can be simplified with ternary operator:
```python
def odd_even(n):
    return "odd number" if n%2 else "even number"
def old_young(age):
    return "children" if age<16 else "young man" if age<50 else "old man"
```

## Task:
Complete function `saleHotdogs`/`SaleHotDogs`/`sale_hotdogs`, function accept 1  parameters:`n`, n is the number of customers to buy hotdogs, different numbers have different prices (refer to the following table), return a number that the customer need to pay how much money.
```
+---------------+-------------+
|  numbers n    | price(cents)|
+---------------+-------------+
|n<5            |    100      |
+---------------+-------------+
|n>=5 and n<10  |     95      |
+---------------+-------------+
|n>=10          |     90      |
+---------------+-------------+
```
You can use if..else or ternary operator to complete it.
