$2.$ Prepare a program that can read a line of input from a terminal. The input can consist of two parts separated by $$:$.$ The left part $($LP$)$ and the right part $($RP$).$ If the size of the LP is greater than the size of the RP then the result will be L$,$ otherwise will be R$.$ If they have the same size but are different then the answer will be D$.$ If the LP and RP are exactly the same then the answer will be S$.$ In case that there is no colon on the line then the answer will be N$.($p$92)($deque$1.$cpp$)$

$*$ Peter: pan count the letter peter $=5$ pan $=4$

Hint: a$.$prepare the queue class with the operations

b$.$prepare the extended queue class with the operations

c$.$in the main using the extended queue will provide the message to insert line with the colon

d$.$from the colon define the left and the right part of the input line
