What is difference between recursion and tail recursion?

Iterations are the looping conditions which continues till a particular condition is met whereas the recursions are related to calling the function itself repeatedly

They are different things recursion: when a part of code calls itself (directly or indirectly) iteration: work in cycle

The original answer really doesn't explain much, and almost nothing that's relevant to the question. (Sorry!) The part about iterations typically involving some kind of loop is on target, though it...

Both Iteration and Recursion run a part of an algorithm repeatedly. We typically use them when, in a part of an algorithm, we have to do or calculate something (i,e. the logic remains the same...

Recursion is repeatedly calling the function.... ---- whereas Iteration is nothing but just looping until condition doesn't satisfy.....
