Encrypt Program ISC Specimen 2023 Theory

A class Encrypt has been defined to replace only the vowels in a word by the next corresponding vowel and forms a new word, i.e. A → E, E  → I, I  → O, O  → U and U  → A. Example : Input: COMPUTER Output: CUMPATIR Some of the members of the class are given below: Class name : Encrypt Data members/instance variables : wrd: to store a word len: integer to store the length of the word newWrd: to store the encrypted word Methods/Member functions : Encrypt(): default constructor to initialize data members with legal initial values void acceptWord(): to accept a word in uppercase void freqVowCon(): finds the frequency of the vowels void nextVowel(): replaces only the vowels from the word stored in 'wrd' by the next corresponding vowel and assigns it to 'newWrd', with the remaining alphabets unchanged void disp(): displays the original word along with the encrypted word Specify the class Encrypt giving details of the constructor, void acceptWord(), void freqVowCon(), void ...

No Repeat Program ISC Computer Science 2022 Semester 2 Theory

Design a class NoRepeat which checks whether a word has no repeated alphabets in it. Example : COMPUTER has no repeated alphabets but SCIENCE has repeated alphabets. The details of the class are given below: Class name : NoRepeat Data members/instance variables : word: to store the word len: to store the length of the word Methods/Member functions : NoRepeat(String wd): parameterized constructor to initialize word = wd boolean check(): checks whether a word has no repeated alphabets and returns true else returns false void prn(): displays the word along with an appropriate message Specify the class NoRepeat, giving details of the constructor, boolean check() and void prn(). Define the main() function to create an object and call the functions accordingly to enable the task. import java.util.Scanner; class NoRepeat{     String word;     int len;     public NoRepeat(String wd){         word = wd;         len = word.le...

Recursion in Python

Recursion is an approach to solve a problem which involves a function calling itself either directly or indirectly. Such a function is known as a recursive function. Every recursive method must have a base case which would stop calling the function again and again indefinitely, because the function stack has a limit, which is platform dependent. A Python program to print a string backwards using a recursive function. def reverse(s, n):     if n > 0:         print(s[n], end = '')         reverse(s, n - 1)     elif n == 0:         print(s[0]) s = input('Enter the string: ') reverse(s, len(s) - 1) A Python program to calculate a b using a recursive function. def power(a, b):     if b == 0:         return 1     else:         return a * power(a, b - 1) a = int(input('a = ')) b = int(input('b = ')) p = power(a, b) print('a to the power b: ' + str(p)...
