Answer:

(c) Router Delay

Explanation:

The network layer of the TCP/IP provides a mechanism or tool for troubleshooting and error messaging called Internet Control Message Protocol (ICMP). Network layer devices such as routers may use this tool to communicate errors especially if there is an issue delivering data packets.

Some of these error messages are;

i. Source Route Failed

ii. Source Host Isolated

iii. Network Unreachable

iv. Host Unreachable

v. Destination Network Unknown

vi. Destination Host unknown

Note:

Router delay is not one of the error messages identified by the ICMP.

Consider the recursive method whose definition appear below. Why? public static String mysteryString (String s){ if(s.length()==
Marizza181 [45]

Answer:

retupmoc

Explanation:

1.) Anwser will be retupmoc

because

public static String mysteryString(String s){

if(s.length() == 1){

return s;

}

else{

return s.substring(s.length() -1) + mysteryString(s.substring(0, s.length()-1));

}

}

In this program input is "computer" . So the function mysteryString(String s) it does

return s.substring(s.length() -1) + mysteryString(s.substring(0, s.length()-1));

so when it enters the first time ??s.substring(s.length() -1) and it will be give you 'r' then it calls the function recursively by reducing the string length by one . So next time it calls the mysteryString function with string "compute" and next time it calls return s.substring(s.length()-1)? + mysteryString(s.substring(0,s.length-1)) so this time it gives "e" and calls the function again recursively . It keeps on doing till it matched the base case.

so it returns "retupmoc".
