Coding & Decoding - 3 Video Lecture | General Aptitude for GATE - Mechanical Engineering

Ans. Coding decoding is a problem-solving technique used in competitive exams to decipher patterns or codes and find the underlying logic behind them. It involves analyzing the given codes or patterns to identify the rule or algorithm used for encoding and decoding.

Ans. To improve your coding decoding skills for exams, you can practice solving coding decoding puzzles regularly. Start with simple patterns and gradually move on to more complex ones. Understand the different types of coding patterns such as letter coding, number coding, symbol coding, etc., and learn the common rules or algorithms used in each type. Analyze the patterns carefully, identify the logic behind them, and practice applying the same logic to similar patterns.

Ans. Some common coding decoding techniques used in exams include: 1. Letter Shifting: In this technique, each letter of the alphabet is shifted a certain number of positions to the right or left. 2. Letter Reversal: This technique involves reversing the order of letters in a given word or code. 3. Letter Substitution: In this technique, each letter is replaced with a different letter based on a specific rule or pattern. 4. Number Manipulation: This technique involves performing arithmetic operations on numbers to obtain the coded value. 5. Symbolic Representation: In this technique, symbols or shapes are used to represent letters or numbers based on a given pattern.

Ans. To quickly solve coding decoding questions in exams, it is essential to practice regularly and develop a strong understanding of the different coding patterns and techniques. Some tips to solve these questions efficiently are: 1. Look for patterns: Analyze the given codes or patterns to identify any recurring patterns or rules. 2. Make a table: Create a table or chart to map the relationship between the original code and the decoded code. This can help you identify the logic more easily. 3. Use options: If multiple options are provided for the decoded code, try substituting each option and check which one follows the given pattern. 4. Eliminate incorrect options: Sometimes, you can eliminate certain options by identifying patterns or rules that are not followed by those options. 5. Practice time management: As coding decoding questions can be time-consuming, practice solving them under timed conditions to improve your speed and accuracy.

Ans. Yes, there are specific strategies to solve complex coding decoding questions. Some strategies include: 1. Break it down: If the given code or pattern seems too complex, try breaking it down into smaller parts. Analyze each part individually and then combine the results to find the overall pattern. 2. Analyze the position: Pay attention to the position of letters or numbers in the given code. Sometimes, the position itself may hold a clue or follow a specific pattern. 3. Look for clues: If any additional information or hints are provided in the question, make sure to analyze them carefully. These clues can guide you towards the correct solution. 4. Guess and check: If you are stuck and unable to find the exact logic, make educated guesses and test them by applying the guessed logic to the given codes or patterns. 5. Practice with complex examples: Regularly practice solving complex coding decoding examples to enhance your problem-solving skills and ability to handle intricate patterns.
