Create a simple guessing game, similar to Hangman, in which the user guesses letters and then attempts to guess a partially hidden phrase. Display a phrase in which some of the letters are replaced by asterisks: for example, G* T*** (for Go Team). Each time the user guesses a letter, either place the letter in the correct spot (or spots) in the phrase and display it again or tell the user the guessed letter is not in the phrase. Display a congratulatory message when the entire correct phrase has been deduced. Add to this the ability for the user to guess the entire phrase. Save the game as SecretPhrase.java.

Add to this an array of 10 phrases to choose from. Generate a random number to use to select one of the phrases from your array.

Also, add a second array to the the alphabet. As the user guesses a letter mark this letter in the alphabet array as used. When the user attempts to use a letter that was already used, tell them that letter was already user to please guess another letter.

Make the game loop so after a round the user can choose to play again and a different phrase will be chosen.

Design an O(n log n) algorithm that takes two arrays A and B (not necessarily sorted) of size n of real numbers and a value v. The algorithm returns i and j if there exist i and j such that A[i] + B[j] = v and no otherwise. Describe your algorithm in English and give its time analysis.

Develop a function to read a document in the MongoDB database “city” in the collection “inspections.” Be sure it can handle error conditions gracefully.
a. Input -> arguments to function should be the key/value lookup pair to use with the MongoDB driver find API call
b. return -> result in JSON format if successful else MongoDB returned error message

(1) Discuss the rules involving actual parameter lists, including matching data types and a one-to-one correspondence with the formal parameter list. Note that the parameter list can be empty, but the function call will still require parentheses after the function name.

(2) Discuss scope rules with respect to global and local identifiers, nested blocks, and functions.

(3) Discuss how local declarations are stored in computer memory. Are there any reasons to avoid using local declarations if it is possible to achieve the same result without them?

Define a class to represent a Temperature. Your class should contain

• Instance variable int fahrenheit
• A parameterized constructor;
• Member method to calculate the equivalent temperature in Celsius unit toCelsius() with decimal value.
  • double toCelsius()
  • Conversion formula: celsius= (fahrenheit - 32) * 5/9
• Method definition to override the equals() method
  • boolean equals(Object obj)

QUESTION 38

1. The ITEM table contains these columns:
   COST NUBMER(7,2)
   RETAIL NUMBER(7,2)
   The RETAIL and COST columns must have a value that is greater than zero.
   Evaluate these two SQL Statements:
   1. SELECT retail – cost * 1.25 * .10
   FROM item;
   2. SELECT (retail – (cost *1.25 )*.10)
   FROM item;
   What will be the results?

   		Statement 1 will return a low value than statement 2.
   		Statement 1 and statement 2 will return the same values.
   		Statement 1 will return a higher value than statement 2.
   		Only one of the statements will execute.
