Understanding the Concepts of Coding and Decoding
Coding and decoding refer to the processes of transforming information or messages from one form to another based on specific rules or algorithms. These concepts are commonly used in computer programming, cryptography, and data transmission.
The following are the important coding and decoding concepts:
1. Letter Coding
In letter coding, the letters in a word are replaced by other letters following a specific pattern to form its code.
The pattern can involve various operations such as shifting the letters by a certain number of positions, adding or subtracting a constant value, or following a sequence of operations.
For Example:
In the given word 'FAUCET' coded as 'GBWEHW', we can observe the following pattern:
F + 1 = G
A + 1 = B
U + 2 = W
C + 2 = E
E + 3 = H
T + 3 = W
Based on this pattern, we can apply the same operations to the word 'CODING' to find its code:
C + 1 = D
O + 1 = P
D + 2 = F
I + 2 = K
N + 3 = Q
G + 3 = J
Therefore, the word 'CODING' will be coded as 'DPFKQJ'.
2. Number or Symbol Coding
Similar to letter coding, number or symbol coding involves replacing letters in a word with numbers or symbols based on given codes. Each letter is assigned a specific number or symbol, and the code for a word is derived by replacing its letters accordingly.
For Example:
In the given word 'WORDS' coded as '3#51@' and 'SEAR' coded as '@9!5', we can observe the following codes for individual letters:
W = 3
O = #
R = 5
D = 1
S = @
E = 9
A = !
Applying the same codes to the word 'DARE':
D = 1
A = !
R = 5
E = 9
Therefore, the word 'DARE' will be coded as '1!59'.
3. Coding based on Substitution
In coding based on substitution, words in a sentence are replaced by other letters, words, numbers, or symbols. Each word is substituted with a specific code or pattern.
For Example:
Given the following codes:
"an endemic is disease" is coded as "pu bt ys ej"
"any disease is curable" is coded as "ar bt xw ej"
"any endemic is not epidemic" is coded as "ys ar mo bt hz"
To find the code for a specific word or decode a given code, we compare the given sentences and identify common words and their corresponding codes.
For example:
"is" appears in all three sentences and its code is "bt".
"disease" appears in the first and second sentences with the code "ej".
"endemic" appears in the first and third sentences with the code "ys".
"any" appears in the second and third sentences with the code "ar".
Based on these comparisons, we can find the codes for other words:
"curable" appears only in the second sentence, so its code is "xw".
"epidemic" appears only in the third sentence, so its code is "mo".
Therefore, the answers to the given questions are:
The word "curable" is coded as "xw".
The word coded as "mo" is "epidemic".
