or this question, you will write a program that takes a sequence $($or any string$)$ and calculates the GC

content $($as a percentage$).$ The result of this calculation will then be displayed to the canvas.

You will test your program with three sequences which can be found in a$4$q$2\_$files.zip:

$1.$ sequence$1.$txt $($a small region of the dog Leptin gene$)$

$2.$ sequence$2.$txt $($the human Sonic Hedgehog gene$)$

$3.$ sequence$3.$txt $($the entire Ebola genome$).$

This program is non$-$interactive, so you won$$t need functions like setup$()$ or draw$().$

Here are the specifications for this problem:

$$ For the purpose of this question, do not worry about ensuring only $$A$,$T$,$C$,$ and $$G$$ characters are

present in the input sequence. This sequence could $($in theory$)$ be any string but only count the $$G$$

and $$C$$ characters.

$$ Hard$-$code the input sequence as a string literal at the beginning of your program. To do this, define

a variable and assign it the value of one of the sequences from the files in a$4$q$2\_$files.zip. Since

we haven$$t covered file input$/$output yet just copy$-$and$-$paste the sequence from the file into your

program.

$$ Use a for$-$loop to count the number of $$G$$ and $$C$$ characters in the input sequence using the variable

you defined at the top of your program.

$$ After the for$-$loop calculate what percent of characters in the string were $$G$$ and $$C$($hint: you might

want to use the len$()$ function$)$
