The input string "Java Program" is defined, and we convert it into a character array. Using a for loop, each character is pushed onto the stack. As the stack follows LIFO, popping elements from it will yield the characters in reverse order, which are stored in a new character array. ...
1、int indexOf(String str) :返回第一次出现的指定子字符串在此字符串中的索引。 2、int indexOf(String str, int startIndex):从指定的索引处开始,返回第一次出现的指定子字符串在此字符串中的索引。 3、int lastIndexOf(String str) :返回在此字符串中最右边出现的指定子字符串的索引。 4、int lastIn...

leetcode reverse string( java) 思路:通过一次循环,将字符串的顺序的拼接,直接用了string类型的加法,超时。 借鉴他人:1.先将string转换为char数组,然后进行转换,最后将char数组转换为string, new String(ch); 2.遍历时,可只遍历一半,然后就行对调操作,时间复杂度O(n/2)...
