Answer:
The method in Java is as follows:
public static String returnlen(String input){
String output = ""+input.charAt(0)+input.charAt(input.length()-1);
return output;
}
Explanation:
This defines the method
public static String returnlen(String input){
This concatenates the first and the last character of the input string
String output = ""+input.charAt(0)+input.charAt(input.length()-1);
This returns the concatenated string
return output;
}
Answer:
Explanation:
p := FIRST(L);
while p <> END(L) do begin
q := p;
while q <> END(L) do begin
q := NEXT(q, L);
r := FIRST(L);
while r <> q do
r := NEXT(r, L)
end;
p := NEXT(p, L)
end;
