In a certain code, FISH is written as HLWM. How is LEAF written in that code?

💡 Solution & Explanation

Compare FISH with HLWM: F → H, I → L, S → W, H → M. The letters move +2, +3, +4, +5 places, one more for each position. Applying the same steps to LEAF: L → N, E → H, A → E, F → K. So the code is NHEK.
