Zottffssentettffssen

Question

Print or return the following string:

zottffssentettffssenttttttttttttttttttttffffffffffffffffffffsssssssssssssssssssseeeeeeeeeennnnnnnnnno

This is the first letter of each of the numbers zero, one, two, all the way up to one hundred.

Standard I/O rules apply, but the output must be exactly as shown above, optionally with a single trailing newline. No other variation in output is permitted. This is code golf, shortest code in bytes wins.

Following the standard calling convention for Unix-like systems (from the System V AMD64 ABI), this takes in RDI a memory address at which to place the result, as a null-terminated byte string.

In assembly:

f:  mov ax, 'z' | 'o'<<8    # Put these two bytes in AX.
    stosw                   # Write them to the string, advancing the pointer.
    .byte 0x48, 0xB8        # Place the following eight bytes in RAX.
    .ascii "ttffssen"
    stosq                   # Write them to the string, advancing the pointer.
    stosb                   # Write the first byte 't' again, advancing the pointer.
    mov BYTE PTR [rdi], 'e' # Place the byte 'e' at the current output address.
    scasb                   # Advance RDI over the 'e' while comparing with AL.
    stosq                   # Write "ttffssen" again, advancing the pointer.
r:  push 10; pop rcx        # Set RCX to 10.
    rep stosb               # Write AL to the string 10 times, advancing the pointer.
    shr rax, 8              # Shift RAX right by 8 bits; AL (its low byte)
                            #  will be each of "ttffssen" in order.
    jnz r                   # Jump back, to repeat, if the result is nonzero.
    mov al, 'o'             # Set AL to 'o'.
    stosw                   # Write 'o' and a null byte, advancing the pointer.

Note

Because of floating point errors, we don't reach exactly k = 0 on the last iteration. That's why we have to use the test k > 0 ? instead of just k ?.

This is still 1 byte shorter than the following integer version:

^{Saved 6 bytes thanks to JvdV}

=LET(a,"ttffssen",CONCAT("zo",a&"te"&a,REPT(MID(a,ROW(1:8),1),10),"o"))

This is only slightly more efficient than just typing the 101 characters manually.

• LET(a,"ttffssen" stores the string ttffssen for later repeated use.
• CONCAT("zo",a&"te"&a combines strings to make the first part. This is only 2 bytes more efficient than hard-coding it.
• MID(a,ROW(1:8),1) turns the 8 character string into an array of 8 characters.
• REPT(MID(~),10) repeats each of those characters 10 times. These last two lines are the big byte-saver I missed the first time. Storing the string as a is not efficient by itself but it is if you later re-use it in the REPT() function.
• CONCAT(~,~,~,"o") add the last letter to the rest of the bits.

---

Original 77 byte version:

="zottffssentettffssen"&CONCAT(REPT({"t","f","s","e","n"},5*{4,4,4,2,2}))&"o"

---

This 78 byte alternative looked like it'd be shorter since each character is repeated the same number of times (allowing you to replace an array with a single integer) but it's only a close second:

="zottffssentettffssen"&CONCAT(REPT({"t","f","s"},20))&"eeeeeeeeeennnnnnnnnno"

---

This 79 byte alternative was an attempt at compressing that array of characters but the savings where offset by the bytes required to convert them to strings:

="zottffssentettffssen"&CONCAT(REPT(CHAR(101+{15,1,14,0,9}),5*{4,4,4,2,2}))&"o"

Answer 25

Just uses the same method as plenty of answers.

out"zo"$A="ttffssen""te"$A;each$A as$v;for$_ in0..9out$v;out'o'

Outputs the expected string, without any trailing whitespace.

Ungolfed

Extremely verbose, almost looking like pseudo-code:

Set $initials to the value "ttffssen".
Show the values "zo", $initials, "te", $initials.

Loop through $initials as $letter.
Begin.
    Loop from 0 to 9 as $i.
    Begin.
        Show the contents of $letter.
    End.
End.

Show the value "o".

More code-y looking:

$initials = "ttffssen";
echo "zo", $initials, "te", $initials;

each $initials as $letter {
    for $i in 0..9 {
        echo $letter;
    }
}

echo "o";

All versions do exactly the same.
