The ISBN is legal if: 1 digit1 + 2 digit2 + 3 digit3 + 4 digit4 + 5 digit5 + 6 digit6 + 7 digit7 + 8 digit8 + 9 digit9 + 10 digit10 is divisible by 11. Example: For an ISBN 1401601499, sum = 1 1 + 2 4 + 3 0 + 4 1 + 5 6 + 6 0 + 7 1 + 8 4 + 9 9 + 10 9 = 253 which is divisible by 11. Write a program to: (i) Input the ISBN code as a 10-digit integer. (ii) If the ISBN is not a 10-digit integer, output the message Illegal ISBN and terminate the program. (iii) If the number is divisible by 11, output the message Legal ISBN .

Question 8 [15] Write a program that encodes a word into Piglatin. To translate word into Piglatin word, convert the word into uppercase and then place the first vowel of the original word as the start of the new word along with the remaining alphabets. The alphabets present before the vowel being shifted towards the end followed by AY . Sample Input(1): London Sample Output(1): ONDONLAY Sample Input(2): Olympics Sample Output(2): OLYMPICSAY Question 9 [15] Write a program to accept the year of graduation from school as an integer value from the user. Using the Binary Search technique on the sorted array of integers given below. Output the message Record exists if the value input is located in the array. If not, output the message Record does not exist . ****All the Best**** 4
