This is wrong. It holds true only when a isn’t equal to b.
you’re limiting the value of the function.

Yup...you have good point....

let me try with different alternative....

This is one alternate way i can think....

a+b= (a2-b2)/(a-b)

def add(x, y):
    while x:
        x, y = ((x & y) << 1), (x ^ y)
    return y

I mean, functions make it simpler kada. What's the point of not using a function? 🤨 you input two integers and return the sum value

Functions use chesina direct + use chesina same ga ?

Run time differ avvuda ? Memory differ untada? #justasking forgoted all the programming skills a decade back

Functions add additional overhead since you have to allocate additional memory and stack space. For a simple function like this, the additional overhead is pretty much negligible. The important use of a function is it's reusablility. Even if it adds additional overhead it's preferred. 

Ok, I misinterpreted your question. If you're asking about direct addition with a '+' vs this function, the answer is bitwise operations are FAST. Using a '+' sign takes more clock cycles than a bitwise operation.

You can still put the same logic without a function (like below) and still get the result  

while x:
        x, y = ((x & y) << 1), (x ^ y)
print (y) # no return statement as it's not in a function

 

C language aa kaka ?

C aithe int x, y; ani mundu variables declare cheyali. Plus the operators are a little bit different
