In java
Remove duplicate letters in a string. Givin a string S of lowercase letters, a duplicate removal consists of choosing two adjacent and equal letters, and removing them. We repeatedly make duplicate removals on S until we no longer can. Return the final string after all such duplicate removals have been made. Example 1 input: "xyyxzx" output: "zx" Explanation: In "xyyxzx", the first round removeal is "yy". After "yy" has been removed, the string is "xxzx". Then, in the next round, "xx" will be removed. "zx" is the final result. Please name your java file as RemoveDuplicates.java
public class RemoveDuplicates { public static void main(String[] args) { // program starts here. } }
