Coding-Decoding: Deciphering patterns in coded messages
🚀 Coding-Decoding is a fascinating topic that involves deciphering patterns in coded messages. Imagine you receive a secret message from a friend, but the words are all jumbled up or replaced with different letters or numbers. Your task is to decode the message and understand what your friend is trying to say. This concept is not only fun but also helps in developing logical thinking and problem-solving skills, which are essential for exams like the JNVST.
Examples💡
Example 1: Suppose the word 'APPLE' is coded as 'BQPMF'. To decode it, notice that each letter is replaced by the next letter in the alphabet. So, 'A' becomes 'B', 'P' becomes 'Q', and so on. If you receive the code 'BQPMF', you can decode it back to 'APPLE'.
Example 2: Let's say the word 'INDIA' is coded as 'JMEJB'. Here, each letter is replaced by the next letter in the alphabet. So, 'I' becomes 'J', 'N' becomes 'M', and so on. If you receive the code 'JMEJB', you can decode it back to 'INDIA'.
Example 3: Consider the word 'RUPPEE' coded as 'SVQQFF'. Each letter is replaced by the next letter in the alphabet. So, 'R' becomes 'S', 'U' becomes 'V', and so on. If you receive the code 'SVQQFF', you can decode it back to 'RUPPEE'.
Common Mistakes to Avoid⚠️
- Mistake 1: Forgetting to check the pattern. Always look for a consistent pattern in the coding, such as shifting letters by a certain number.
- Mistake 2: Confusing the order of letters. Ensure you follow the sequence correctly when decoding.
- Mistake 3: Overlooking exceptions. Sometimes, the pattern might change for certain letters, so be attentive to any irregularities.
