R + 1 = S
E is the second vowel in the alphabet series. So, E is coded as 2.
Q + 1 = R
U is the fifth vowel in the alphabet series. So, U is coded as 5.
E is the second vowel in the alphabet series. So, E is coded as 2.
S + 1 = T
T + 1 = U.
Similarly,
We can decode ACID as:
A is the first vowel in the alphabet series. So, A is coded as 1.
C + 1 = D
I is the third vowel in the alphabet series. So, I is coded as 3.
D + 1 = E
So, ACID is coded as 1D3E.
