Consider the following code segment, which uses properly declared and initialized int variables x and y and the String variable result.     String result = “”; if (x < 5){ if (y > 0) { result += “a”; } else { result += “b”; }}else if (x > 10){ if (y < 0) { result += "c"; } else if (y < 10) { result += "d"; } result += "e";}result += "f";     What is the value of result after the code segment is executed if x has the value 15 and y has the value 5?

Consider the following code segment, which is intended to print the digits of the two-digit int number num in reverse order. For example, if num has the value 53,  the code segment should print 35. Assume that num has been properly declared and initialized.   /* missing code */ System.out.print(onesDigit);System.out.print(tensDigit); Which of the following can be used to replace /* missing code */ so that the code segment works as intended?

If an integer variable diameter currently holds the value 5, what is its value after the following statement is executed?             diameter = diameter * 4; If it shows an error, just type error.

Consider the following code segment.   for (int j = 1; j = 1; k–) // Line 3 { System.out.print(j + ” “); // Line 5 } System.out.println();}     The code segment is intended to produce the following output, but does not work as intended.    12 23 3 34 4 4 4    Which of the following changes can be made so that the code segment works as intended?

In the following code segment, n is a properly declared and initialized int variable.     boolean result = false; if (n >= 10){ result = true;}if (n

What does the following Python code display? print(“3”) print(“2”)print(“1”) print(“Blast off!”)

In Python, list is mutable (can be changed after it’s created).

What is the output of the following code fragment? Assume all the variables are declared.   if(( 5.2 > 3.3 && 6.2 < 9.9) && (6.2 < 3.5 || 4.2 == 3.1 || 3.1 != 3.14)) {       System.out.print("TRUE");}else {     System.out.print("FALSE");}

Which type of exception must be explicitly handled or declared in Java?

Caesar ciphers, also known as shift ciphers, use a substitution method where letters in the alphabet are shifted by _____________________ to yield an encoding alphabet.
