Solving Coding - Decoding Problems

Coding is a process used to encrypt a word, a number in a particular code or pattern based on some set of rules. Decoding is a process to decrypt the pattern into its original form from the given codes.

Coding is basically a combination of letters, numbers, and symbols.

Types of Coding-Decoding Problems:
1. Letter Coding
2. Number Coding
3. Number to letter coding Type
4. Substitution Coding


1. Letter Coding

Letter coding are based on alphabets or word. which is given on some pattern which is look like a code and candidate need to analyze the pattern and give the answer according that.

In Letter coding type question you need to analyze the given coding pattern according that obtain the answer. First you have to observe the both letter code then notice the position of letters and search the common pattern.

Example 1: In a particular code language TALK is code as UBML, How is BACK code in same language?
Solution:
Each and every letters are in TALK word move +1 to obtain the similar letter.
T +1 U B +1 C
A +1 B A +1 B
L +1 M C +1 D
K +1 L K +1 L

Example 2: In a particular code language FEBRUARY is code as HGDTWCTA, How is AUGUST code in same language?
Solution:
In code language each letter of FEBRUARY is code as increased +2 letter become HGDTWCTA. similarly AUGUST each letter code as CWIWUV which has increased +2 each letters.

Example 3: In a particular code language LIMITED is code as OLPLWHG, How is INVITED code in same language?
Solution:
In code language each letter of LIMITED is code as increased +3 letter become OLPLWHG. similarly INVITED each letter code as LQYLWHG which has increased +3 each letters.

Example 4: In a particular code language SONY is code as XTSD, How is TONY code in same language?
Solution:
In code language each letter of SONY is code as increased +5 letter become XTSD. similarly TONY each letter code as YTSD which has increased +5 each letters.

Example 5: In a particular code language MOUSE is code as NQXWJ, How is CLOCK code in same language?
Solution:
In code language each letter of MOUSE is code as increased +1,+2,+3,+4,+5 way, become NQXWJ. similarly CLOCK each letter code as DNRGP which has increased +1,+2,+3,+4,+5 each letters same way.

Example 8: In a particular code language SHIFT is code as YJLJT, How is PRINT code in same language?
Solution:
In code language each letter position of SHIFT note down as ascending order like 1,2,3,4,5 then outcome code would be in descending order like 5,4,3,2,1 OR YJLJT. Similarly letter position of PRINT note down as ascending order like 1,2,3,4,5 then outcome code would be in descending order like 5,4,3,2,1 OR YRLTQ.

Solution:
In code language each letter position of TIGER is places decreased by -2 letter become RGECP. similarly WOMEN each letter code as UMKCL which has decreased by -2 each letters.

Example 10: In a code language INDIA is code as QLFDL, how KENYA will be code in same language?
Solution:
In code language each letter of INDIA as 1st two from left and last two from right of a letter is code cross position places which increased +3 letter and middle letter has increased +2 which has positioned in middle become QLFDL. similarly KENYA each letter code as HNPDB which has increased in same pattern letters.


2. Number Coding

Number coding problems are based on numbers given on some pattern which looks like a code and candidate need to analyze the pattern and give the answer according that.

To solve, first you have to observe the both Number code then notice the position of Number and search the common pattern.
