Sorry, but I don't think this algorithm is a good addition. It's pretty much trivial (esp. if seen as check palindrome + check charset) and solves an oddly specific problem.
(Code-wise it's mostly fine though, but should return a bool rather than strings.)

@raklaptudirm thoughts?

ok , no issues i will come up with a new algo

My advice: Try to stick to generally useful nontrivial standard algorithms. For example Push-Relabel if you want to implement a network flow algorithm. You will ideally learn more (for this, first fully understand the algorithm, then implement it from scratch / memory) and your contributions will be more interesting and useful.
