Coding-Decoding: Deciphering patterns in coded messages
🚀 Coding-Decoding is a fascinating topic that involves understanding and deciphering patterns in coded messages. Imagine you and your friend have a secret language that only both of you understand. You use this language to send messages that others cannot easily understand. In coding-decoding, we learn how to create such secret codes and how to break them to understand the hidden messages. This concept is not only fun but also sharpens your logical thinking and problem-solving skills.
Examples💡
Example 1: Suppose the word 'APPLE' is coded as 'BQPMF'. To decode it, notice that each letter is shifted by one position forward in the alphabet. So, 'A' becomes 'B', 'P' becomes 'Q', and so on. To decode 'BQPMF', shift each letter back by one position to get 'APPLE'.
Example 2: If 'CAT' is coded as 'DBU', then to decode 'DBU', shift each letter back by one position in the alphabet. 'D' becomes 'C', 'B' becomes 'A', and 'U' becomes 'T', resulting in 'CAT'.
Example 3: In a number code, if '123' is coded as '234', then to decode '234', subtract 1 from each digit to get '123'.
Common Mistakes to Avoid⚠️
- Mistake 1: Forgetting to apply the same pattern consistently. Always ensure that the same rule is applied to each letter or number in the code.
- Mistake 2: Confusing the direction of the shift. Remember whether you need to shift forward or backward in the alphabet or number sequence.
- Mistake 3: Overlooking exceptions or special rules in a given code. Pay attention to any specific instructions or patterns that might be unique to the code.
