In a certain code language, RINGS is written as IRNSG, and PURSE is written as UPRES. How will STORM be written in that language?

Let's look at the arrangement logic:
For RINGS → IRNSG:

The letters are grouped or re-arranged in pairs/positions.

Positions: 1-2-3-4-5 → R-I-N-G-S

Swapping the first two letters: R I → I R

Swapping the next two letters: N G → G N (Wait, let's look closely at IRNSG)

Let's check indices:

1st letter (R)→2nd position

2nd letter (I)→1st position

3rd letter (N)→3rd position

4th letter (G)→5th position

5th letter (S)→4th position
Hence, (1,2,3,4,5)→(2,1,3,5,4)

Let's verify with PURSE → UPRES:

(1,2,3,4,5)→P, U, R, S, E

Rearranged to (2,1,3,5,4)→U, P, R, E, S
This matches perfectly.

Applying the same pattern to STORM:

Positions: 1=S,2=T,3=O,4=R,5=M

Rearranged positions (2,1,3,5,4)→T, S, O, M, R

Therefore, STORM becomes TSOMR.
