In a certain code language, 'ALPHA' is written as 'MBPBI' and 'GAMMA' is written as 'BHMBN'. How will 'LASER' be written as in that language?

The pattern follows a reverse-position shift combined with adding +1 to positional values. Let's analyze the words by reading from the last letter to the first letter:
For 'ALPHA':

Last letter A+1=B

Fourth letter H+1=I

Third letter P+1=Q (Wait, let's examine the exact mapping)

Let's re-examine the direct mapping or structural division:
Split 'ALPHA' into two halves: 'AL', 'P', 'HA'
Alternatively, reverse the word 'ALPHA' → 'AHPLA'
Let's see the transformation from 'ALPHA' to 'MBPBI':
A→M
L→B
P→P
H→B
A→I

Let's check the reverse mapping:
A (last)+1=B (placed at 2nd position?)
Let's look at the vowels and consonants or a cross pattern:
A→B (last letter shifts to second position)
H→I (fourth letter shifts to fifth position)
L→M (second letter shifts to first position)
P→P (middle letter remains same?)

Let's look at the cross pattern systematically for a 5-letter word:
1st letter A+1=B (moved to 2nd position)
2nd letter L+1=M (moved to 1st position)
3rd letter P+0=P (moved to 3rd position)
4th letter H+1=I (moved to 5th position)
5th letter A+1=B (moved to 4th position)

Let's verify this pattern with 'GAMMA' → 'BHMBN':
1st letter G+1=H (moved to 2nd position)
2nd letter A+1=B (moved to 1st position)
3rd letter M+0=M (moved to 3rd position)
4th letter M+1=N (moved to 5th position)
5th letter A+1=B (moved to 4th position)
This matches 'BHMBN' perfectly!

Now apply the same pattern to 'LASER':
1st letter L+1=M → moves to 2nd position
2nd letter A+1=B → moves to 1st position
3rd letter S+0=S → moves to 3rd position
4th letter E+1=F → moves to 5th position
5th letter R+1=S → moves to 4th position

Arranging them:
1st: B
2nd: M
3rd: S
4th: S
5th: F

The resulting code is 'BMSSF'.
