What will be the output of the program?
public class DailyDoseC {
public static void main(String[] args) {
String inputString = "reactwall";
char characters[] = inputString.toCharArray();
System.out.print(meth(characters));
}
private static String meth(char[] input) {
int totalIndex = input.length;
int writeIndex = 1;
if (input[0] == 'b') { writeIndex = 0; }
for (int i = 1; i < totalIndex; ++i) {
if (input[i] == 'b') { continue; }
if (input[i] == 'c') {
if (input[writeIndex - 1] == 'a') {
writeIndex--;
continue;
}
}
input[writeIndex] = input[i];
writeIndex++;
}
return new String(input, 0, writeIndex);
}
}
