Input

A string s of printable ASCII characters, newlines, and spaces (0x20 ( ) to 0x7E (~)), and a non-negative integer n.

Challenge

To write a program that outputs either another program, or s depending on n. If n = 1, Then your code should output code which outputs s. If n = 2, Your code should output code which outputs code which outputs s and so on.

All outputted code should be in the same language as the language of the original submission.

Test Cases

Format: s, n -> output
Assuming your submission is written in JavaScript:

No cycles, 0 -> No cycles
Hello, 1 -> console.log("Hello");
Cycle!, 3 -> console.log("console.log("console.log(\"Cycle!\")")");
:), 3 -> console.log("console.log('console.log(`:)`)')");

Scoring

This is code-golf, so aim for shortest code in bytes.

Additional Rules

• I/O format is flexible


• Default rules and standard loopholes apply.


• The output of your submission must be valid.


• You can use any language, even if it was created after this challenge, as long as it wasn't created for the purpose of this challenge


• This isn't a polyglot challenge. A JavaScript submission shouldn't output Ruby code.


• Input is guaranteed to be valid as defined in the Input section

Validation

Here's a quick tip to test your answers:

For n=0, output=s

For n=1, eval(output)=s

For n=2, eval(eval(output))=s

Where n and s are inputs

code-golf string

Google Sheets, 96 bytes

=Join("",If(B1,ArrayFormula("="&Rept("""",2^(Row(Offset(A1,0,0,B1))-1))),),A1,Rept("""",2^B1-1))

Inputs are in cells A1 (s) and B1 (n).

^{(Columns D, E, and F show the result if you copy the output from the column to its left and input it as a formula.)}

---

The formula concatenates 3 pieces into a single string. The first piece is the most complicated.

If(B1,ArrayFormula("="&Rept("""",2^(Row(Offset(A1,0,0,B1))-1))),)

If If statement drops the prefix if n=0 so you end up with No cycles instead of ="No cycles. The ArrayFormula creates an array of equal signs followed by some number quotes. That number is 2^(x-1) where x counts up from 1 to n thanks to the Row(Offset(~)) combination.

The next piece (A1) adds in s and the final piece (Rept("""",2^B1-1)) adds in 2^n-1 quotes at the end.

function($s,$n)while($n--)$s='echo'.var_export($s,1).';';return $s;

Try it online!

From the documentation about var_export:

var_export — Outputs or returns a parsable string representation of a variable

This function calls var_export prepends echo and appends ; $n times.

=Join("",If(B1,ArrayFormula("="&Rept("""",2^(Row(Offset(A1,0,0,B1))-1))),),A1,Rept("""",2^B1-1))

Inputs are in cells A1 (s) and B1 (n).

The formula concatenates 3 pieces into a single string. The first piece is the most complicated.

If(B1,ArrayFormula("="&Rept("""",2^(Row(Offset(A1,0,0,B1))-1))),)

If If statement drops the prefix if n=0 so you end up with No cycles instead of ="No cycles. The ArrayFormula creates an array of equal signs followed by some number quotes. That number is 2^(x-1) where x counts up from 1 to n thanks to the Row(Offset(~)) combination.

The next piece (A1) adds in s and the final piece (Rept("""",2^B1-1)) adds in 2^n-1 quotes at the end.
