Number chopping: Split a number into its digits [closed]

Question

Number Splitting

Instructions

Oh no, my numbers have stuck together! Luckily, we can split them apart with code.

Your code should be a function that takes an integer input from stdin or as an argument. You must split the number into single digits, keeping the order and possible duplicates of these digits. The output should be an array and it may be returned from the function or from stdout. Other forms of output may be discussed. The array elements may be a string or number.

Examples

345 -> [3, 4, 5]
12218 -> [1, 2, 2, 1, 8]

Scoring

This is code golf, so shortest code wins.

\B
,

Try it online! Explanation: Simply inserts a , between each pair of digits. Alternatively, if a newline-delimited list is acceptable, then for 3 bytes:

!`.

Try it online! Explanation: Simply lists each digit separately. Alternatively, to produce the example output, then for 13 bytes:

\B

Explained

  _  The current input (implicit)
 \   Map/Fold by this:
_    The current item of the input, overloaded by \

     Thus, Map/Fold yields a list of the items of the input string.

Answer 7

Assembly (MIPS, SPIM), 106 bytes

Outputs the digits space-separated.

.data
.text
main:li $v0,12
syscall
move $a0,$v0
beq $a0,10,e
li $v0,11
syscall
li $a0,32
syscall
b main
e:

Assembly (MIPS, SPIM), 160 bytes

This outputs in a format looking like a list of digits.

.data
.text
main:li $a0,91
li $v0,11
syscall
l:li $v0,12
syscall
move $a0,$v0
beq $a0,10,e
li $v0,11
syscall
li $a0,44
syscall
b l

Answer 8

Javascript(ES6), 38 bytes

Just to kick this off.

a=(w)=>{return w.toString().split("")}

Output:

345 -> ["3", "4", "5"] 12218 -> ["1", "2", "2", "1", "8"]

Answer 9

Python 2, 18 bytes

lambda x:list(`x`)

Python 3, 21 bytes

lambda x:list(str(x))

Answer 10

Python 3: 28 20 bytes

Try it Online - lambda function

Try it Online - normal function def

Tried it with lambda function (20 bytes) instead of normal function definition

x=lambda n:[*str(n)]

My earlier response with normal def function - 28 bytes

def x(n):*x,=str(n);return x

Calling the function as follows:

print(x(345))
print(x(12218))

Output:

['3', '4', '5']
['1', '2', '2', '1', '8']

Answer 11

C (gcc), 36 bytes

Returns a string representation of the integer.

f(i){int*s;asprintf(&s,"%d",i);i=s;}

Answer 13

Pyth, 3 bytes

jQT

Explanation: Takes the integer input (Q) and converts it into base 10 (T) and returns the individual digits in a list.

Unlike the above one, this one takes input as a string and returns an array of the characters of the string. Still 3 bytes. :<)
