This is a REPL on stdin/stdout. Expects every line to be a full statement or empty. eval is used to shorten the implementation, but is otherwise not necessary for logic.

Positional Awareness
Your task is to generate a program that, for every permutation of its characters (which includes the original program), outputs the positions of every character relative to the original program.
If your program is
Derp
you must output
[0, 1, 2, 3]
(or some equivalent)...
The question is to find the sum of Digit XOR till N.
For eg:-
Digit XOR of a number 112
112 => 1 xor 1 xor 2 = 2
So we need to find
int digit_xor_sum=0
for(i=1;i<=N;i++){
digit_xor_sum+= digit_xor(i);
}
return digit_xor_sum
My Solution Approach was as follows,
int digit_xor(int n)...
Shortest self-destruction loop
Your task is to write a full program or function that takes no input and runs any type of loop (while, for, foreach, do, do-while, do-loop, goto, etc) that will end in causing an error.
Rules:
This is code-golf so the shortest code wins.
The loop must produce at...
Task
Your task is to write a program that will take input, and then output the lyrics to We Are Number One, changing specific words. The input will contain both the words to be changed, and the replacement word.
Input
The input will be in the following format:
one, two\n
net, villain\n

Stackylogic is a logic-based programming language I made up that take in 0's and 1's for input and outputs a single 0 or 1 upon completion.
A Stackylogic program consists of lines that can only contain the three characters 01? as well as exactly one < at the end of one of the lines. Lines may no...
