Coding is the process of encrypting a word, a number, or a pattern in a certain pattern or code based on the rules which are set.
The process of decrypting a pattern into its original form from provided codes is known as decoding.
In competitive examinations, you will encounter several sorts of coding and decoding problems. Few of the most prevalent varieties are listed below:
In this technique of coding and decoding, the letters of the word are coded utilizing different operations including subtraction, addition, interchanging, and many more. Candidates must decode or change the code of other words using the same procedures.
A term is assigned numerical code merit, or a number is allocated to alphabetically code letters, in this type of coding-decoding.
In this type of coding-decoding, words are encrypted or coded with the relevant keyword.
In this type of coding-decoding, numbers between 1 to 12 are coded, and inquiries are responded according to clock timing.
In this type of coding-decoding, binary values such as 0 and 1 are utilised to encode decimal integers.
In this type of coding-decoding, a few methods will be taught, and applicants must apply all of the provided conditions to obtain the code of a certain word.
Because a word or a sentence is coded by shifting the locations of English alphabet letters in a certain pattern, it’s important to memorise the positions of all the letters in English alphabetical order, both forward and backward.
With the help of this basic principle, you may simply memorise the placements of alphabets and discover the placement of any letter without much effort. However, it is recommended that you master the alphabet’s letter positions.
E | J | O | T | Y |
5 | 10 | 15 | 20 | 25 |
Lets solve a Coding and Decoding Problem with the help of EJOTY technique. For example, we’re supposed to discover the 24th letter from the alphabet’s left side. We already know that the 25th letter from the left is Y; now we must locate the letter preceding Y, which is X. We can simply discover the location of any letter in the alphabet using this easy approach. It is necessary to memorise the places and sequence of letters in order to solve any problems.
This is vital to be aware of some methods that will assist you in swiftly salting questions throughout your preparation for the topic of coding-decoding.
For more information, see the approaches listed below.
Q.1 If the decoded value of ‘FROZEN’ is ‘OFAPSG’. Select the correct option that shows ‘MOLTEN’ written in this manner.
Explanation:
To answer this question, simply invert the word and add one to each letter. NETLOM is the alphabetically opposite of MOLTEN. The code for MOLTEN becomes OFUMPN if we add 1 to each letter.
So ans is (c)
Q.2 HARYANA is written as 8197151 in a certain code; how is DELHI written in that code?
Explanation:
We utilised the number of alphabets as a solution.
H = 8
A = 1
R = 18 = 1+8 = 9
Y = 25 = 2+5 = 7
For DELHI
D = 4
E = 5
L = 12 = 1+2 = 3
H = 8
I = 9
As a result, DELHI is abbreviated as b) 45389.
Q.3 If January is called “March”, March is called “April” and April is called “May”, then which of the listed months will have only 30 days?
Explanation:
January, March and May have 31days and April has 30 days.But April is called May so the answer is (d) May.
So that’s how Coding and Decoding Questions are solved.
Coding-decoding encompasses all areas of learning and aims to improve children’s logical thinking abilities as well as their capacity to recognise distinct sounds that makes up words. Coding-decoding aids in the development of children’s fluency, vocabulary, understanding, and exposure to phonemic terms.
Coding-decoding aids in the understanding of how communication occurs. There are several types of coding-decoding that may be used to learn how to match patterns with numbers, symbols, and letters. The reasoning booster for improving reading abilities and comprehension is coding-decoding.
