Correct answer for first 4 test cases but run-error occured in last 2 test cases.
CODE:
import java.util.;
import java.io.;
public class Main {
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String str = br.readLine();
camel(str);
}
public static void camel(String str) {
for(int i = 0; i < str.length(); ) {
if(Character.isUpperCase(str.charAt(i)) && Character.isUpperCase(str.charAt(i+1))) {
System.out.println(str.charAt(i));
i++;
}
StringBuilder sb = new StringBuilder();
sb.append(str.charAt(i));
i++;
while(!Character.isUpperCase(str.charAt(i))) {
sb.append(str.charAt(i));
i++;
if(i == str.length())
break;
}
System.out.println(sb);
}
}
}
