Introduction To Algorithm

The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results. 

Advantages of Algorithms:

  • It is easy to understand.
  • Algorithm is a step-wise representation of a solution to a given problem.
  • In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program.

Caesar Cipher – Hacker Rank Solution


Julius Caesar protected his confidential information by encrypting it using a cipher. Caesar’s cipher shifts each letter by a number of letters. If the shift takes you past the end of the alphabet, just rotate back to the front of the alphabet. In the case of a rotation by 3, w, x, y and z would map to z, a, b and c.

Original alphabet:      abcdefghijklmnopqrstuvwxyz
Alphabet rotated +3:    defghijklmnopqrstuvwxyzabc


The alphabet is rotated by , matching the mapping above. The encrypted string is .

Note: The cipher only encrypts letters; symbols, such as -, remain unencrypted.

  4. Mentre le carte di valore elevato (A, 10, J, Q, K) tendono a favorire i conteggiatori di carte, la casa ha una migliore possibilità di vincita pescando carte di basso valore (2 – 6). Con il resto delle carte (7 – 9) nessuno dei due ha un vantaggio. Quando si entra in un casinò è impossibile non fermarsi a un tavolo di Blackjack per provare uno dei giochi più famosi e amati di sempre. Se il giocatore ha un punteggio superiore al banco, vince l’importo che ha scommesso inizialmente. Se invece il suo punteggio è minore del mazziere perde la puntata. Se i due punteggi sono uguali, la mano è considerata patta, mentre se il giocatore sballa, il giocatore perde la sua posta, anche se il mazziere dovesse sballare. Raccogliendo 21 punti con due carte, scoprirà di essere in possesso di BlackJack. Questo accade quando si combina una figura con un Asso. Quindi può vincere, anche se il casinò raccoglie 21 con 3 o più carte. Se anche il casinò ha il Black Jack con due carte, le mani pareggiano.
