Suppose we have the following two strings:

string a $=$ "Frodo";

string b $=$ "Sam";

Write the result of the following statements. Use the original a and b for each problem.

$1.)$ cout $<<$ a$.$substr$(1,3)$;

$2.)$ cout $<<$ b $+$ a$.$substr$(3,2)$;

$3.)$ b$.$insert$(2,$ a$)$;

cout $<<$ b;

$4.)$ a$.$erase$(3,2)$;

cout $<<$ a $+$ b;

$5.)$ string c $=$ a$+$b;

cout $<<$ setw$(10)<<$ a;

cout $<<$ setw$(10)<<$ c;

$6.)$ a$.$erase$($ a$.$find$(0,"$o$"),2)$;

cout $<<$ a;

$7.)$ Write a single line of code that deletes the first letter $"$Q$"$ in a given string s
