Consider the following series and the steps applied to it: Initial series: F 3 6 N @ 9 K T Q 5 C % 8 B # 7 D S ∗ H 4 W L F \, 3 \, 6 \, N \, @ \, 9 \,...

Consider the following series and the steps applied to it:

Initial series:

Step I: The numbers which are immediately preceded by a symbol and immediately followed by an alphabet are moved to the end of the series in increasing order (placed immediately after L).

Step II: The odd numbers which are immediately preceded by an alphabet swap their positions with the alphabet immediately before them.

Step III: The alphabets which are immediately followed by a symbol are arranged in alphabetical order between H and 4 of Step II.

Question: How many alphabets in Step II are immediately preceded and immediately followed by numbers?
