from A to B and B to A.
That is q's A B B A A B
after Step 1 i.e interchange 2 and 5.

SECTION II

1. Given the function f(n a b c ) = ac if n=1
f(n a b c) = f( n-1 a b c) + f( 1 a b c) + f( n-1 b a c )
if n > 1
f( 2) = ?
Ans: f( 2 a c b ) = ab + ac + bc.

2. similar question in functions.
3. [ based on function in 1.] f( 4 a b c ) the number of terms is...?
Ans: f( 4 a b c ) = f( 3 a c b ) + f( 1 a b c ) + f( 3 b a c ) etc.
= 5ab + 5ac + 5bc.
4. f( 5 a b c ) = ?
