Coding and decoding are used in defence service and any other service for secret message.In coding a word is coded by various pattern.
Coding and decoding is easy to learn - You will enjoy it.
Coding and decoding is classified in three types:
In jumbled pattern the word are in specific pattern, that pattern should be applied to other words.
In Substitution pattern the word is substituted by a letter or number.
In a certain code “APPLE” is coded as 23125, “LAP” is coded as 312, “CAP” is coded as 214 then “LEAP” = ?
Answer: 2) 3512
Explanation: In APPLE , P is repeated twice . So P = 2 . In the above three words 'A' is common , so A = 1. In LAP, A = 1 and P = 2, so L = 3. In APPLE , P = 2, A = 1, L = 3, then E = 5. So LEAP can be coded as 3512.
In shifting pattern every letter is written as another letter following a definite patterns.
Normal shifting pattern: in this pattern the letter of the word following a unique shifting pattern.
Ex: In a certain code language PURPOSE is coded as OVQQNTD. How is PATTERN coded in the language.1)OBSUDSM
Explanation: Here, every alternative starting from first letter is shifted one place and every alternative letter starting from the second letter is shifted one place forward.
