This article introduces the knowledge of "how to reverse strings in Java". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Topic: reverse the string according to k.

/ * 0k 2k 3k * |-- * +-- reverse--+ +-- reverse--+ * /

Every 2k characters, reverse the first k characters. If less than k characters, reverse all characters. If the number of characters greater than or equal to k is less than 2k characters, the first k characters are reversed and the remaining characters remain unchanged.

Idea: use the reverse function to reverse. The code is still simple.

Language: cpp

Class Solution {public:string reverseStr (string s, int k) {for (int I = 0; I < s.size (); I + = 2qk) {reverse (s.begin () + I, min (s.begin () + iDek, s.end ();} return s;}; this is the end of the introduction of "how to reverse strings in Java".
