Leave asterisks or spaces.

Find the maximum and minimum values, calculate the relative values as a percentage, display each rectangle by multiplying the screen height of the rectangle taken as 100% by the percentage.
If in the console, then you can display the character "\u2592" or asterisks, filling the height of each rectangle with them. A histogram can be drawn horizontally or vertically.

This is a difficult task for a beginner.
1. First you need to make a lexical analyzer that separates the text into tokens. Also, loops can be nested - a token within a token.
2. Here, and then, when you have a stream of tokens, you can count the corresponding tokens - get an array of quantities.
3. When you have an array of quantities, you can pass it to the histogram builder.
Building a histogram is the easiest part of this whole task.
