I have doubt what will we be the value of pattern at beginning , i 'm unable to decode that iif condition could explain one sample taking rough records in paper

[@jayashree.j1777]

At the begining, current_id != prev_id, so pattern takes department value.
In this scenario, the first value of pattern will be 'A'.
