As we know all numbers can be represented by a fibonacci number. 1 2 3 5 8 13 21 34 55 89 Suppose 6 = 5 + 1, can be encoded as 1001 16 = 13 + 3 = 100100 4 = 3 + 1 = 101 Similarly, all the letters "a-z and A-Z" should be converted to ASCII number then convert them to Fibonacci encoded number Then read decode them back to origonal character. H E L L O ASCII values of all the letters from (HELLO) Then covert them to corresponding binary values e.g H = 72 = 55 + 13 + 3 + 1 = 100100101 And add "1" (number 1) to end of all charcter to find out the number ends there. So H = 100100101 + 1 = 1001001011 (Not mathematical add, string add or append) 4. What you like to do in leisure time? 5. What you have done something interesting beyond your scope? 6.
