if we have this little code

 

 

function sum (){var a = 135;var d = a << (150 - a % 32);var c = d << (160 % 53 + 3*2 +7);var y = 78945666 - d ;var b = a+d+c+y ;return b ;}

 

what does it mean to reverse it that is what does it mean to reverse a code??

 

does it mean that we should reverse the operators of the code like this :

 

 

function reverse sum(){var a = 135 ;var d = a >> (150 + a % 32);var c = d >> (160 % 53 - (3/2)-7);var y = 78945666 + d ;var b = a+d+c+y ;return b;}

 

or it means that we should begin the code from the bottom to the top

 

like this function reverse sum()

 

{

var b = a+d+c+y ;

var y = 78945666 - d ;

var c = d << (160 % 53 + 3*2 +7);

var d = a << (150 - a % 32);

var a = 135;

}

I assume what it means is to create a function that takes what the other one outputs and return what was put into it. That is, if function A takes in 5 and outputs 23, then function B needs to take in 23 and output 5.

 

Your code doesn't seem to have any inputs, so perhaps that definition doesn't fit. Where did you find the question?

[hisoka]

both functions are not related in anyway and the same for their output . I put them only to make my question more clear. Generally and in the context of programming, what does it mean to reverse a code or a script ? does it mean that the execution begins from the bottom to the top ? or that the operators are reversed 1+1 = 2 becomes 1-1=0 ? or that the result of the execution of the code is reversed like 01001000 binary becomes 10110111 or false becomes true ? or 150 becomes -150?

Can you point to an article where you read about reversing code? It depends on the context.

 

Reversing a string means putting the letters in reverse order, "Hello, World!" becomes "!dlorW ,olleH"

Reversing a function would be to make a function that does the opposite, which I explained in my previous post.

Reversing the order of execution would mean writing the lines of code in reverse order.

"Reversing the order of execution would mean writing the lines of code in reverse order"

 

Interesting . but what do you mean in reverse order ? you means from the bottom to the top ? Can you please give me a clear and short example on how to write the lines of the code in the reverse order as you wrote ?

 

execution from the top to the bottom

 

a+b=c;

 

c+d=e;

 

e+f=g;

 

when you reverse it it becomes like this :

 

execution from the bottom to the top

 

e+f=g;

 

c+d=e;

 

a+b=c;

 

is this what you mean?

[Ingolme]

Yes. But I have no idea what you're really asking for. "reverse" has so many different meanings depending on the context.

[hisoka]

yes you are right . It depends on the context
