ASCII Charts (Part 2: Bar Chart)

Given a dictionary containing quarterly sales values for a year, return a string representing a bar chart of the sales by quarter.

• Quarter names (Q1, Q2, Q3, Q4) should appear on the left.
• Quarters should be sorted in descending order by value.
• Quarters with the same value should be shown in their yearly order (Q1 -> Q4).
• Bars should begin with a "|".
• Repeat the character "#" to fill the bar, with each character having a value of 50.
• A single space comes after the bar, then the sales for that quarter.
• If the value is 0, there should be no space after "|".
• Use the newline character ("\n") to separate each bar in the chart.

Example #1

bar_chart({"Q4": 250, "Q1": 300, "Q2": 150, "Q3": 0})
➞ "Q1|###### 300\nQ4|##### 250\nQ2|### 150\nQ3|0"

When printed:

Q1|###### 300
Q4|##### 250
Q2|### 150
Q3|0

Example #2

bar_chart({"Q4": 500, "Q3": 100, "Q2": 100, "Q1": 150})
➞ "Q4|########## 500\nQ1|### 150\nQ2|## 100\nQ3|## 100"

When printed:

Q4|########## 500
Q1|### 150
Q2|## 100
Q3|## 100

Notes

There should be no additional whitespace after each value.
