Algorithms & Programming Fundamentals
In a situation where the program's outcome must adapt to user input in real-time, which programming structure is most effective for handling such conditions?
If-else statements
Preprocessor directives
Infinite loop
Constant variable declaration
What is the purpose of selection statements in programming?
To control the flow of execution in a program
To specify requirements for input data
To define variables in a program
To perform mathematical calculations
What is the purpose of the condition in an if statement?
To execute a specific piece of code
To define a function
To evaluate whether a certain condition is true or false
To initialize a variable
Which part of an if-else statement is executed when the condition is false?
Code inside the else statement
Code inside the function
Code inside the if statement
Code inside the loop
When designing a game in which a player's move is only valid if they have not previously occupied that space, which data structure would effectively track these moves?
Set collection
Array list
Stack
Priority queue
What does the "if" keyword represent in most programming languages?
A function definition
A conditional statement
An error handling method
A loop structure
Which type of control structure would you use to execute one set of code when a variable equals 10
and another set when it does not?
If-else statement
For loop
Switch Statement
While loop

When designing algorithm involving use recursion includes base case series recursive calls involves branching based different conditions how does choice affect scalability solution?
Reduced recursion depth limits stack growth and avoids issues with large input sizes, allowing for predictable resource allocation.
Direct mapping of iterations onto processing cores leads to better parallelization, though it might introduce overhead in communication and synchronization.
Increased tail call optimizations reduce the risk of stack overflow, maintaining high performance under heavy load.
Recursive approach scales well for problems that exhibit a natural hierarchical structure, allowing for divide and conquer strategies.
What will be the output if the following pseudocode is executed?
IF (age > 18) THEN PRINT "Adult"
ELSE PRINT "Minor"
END IF
No output since there's no ELSE IF statement.
Adult or Minor depending on whether age is greater than 18.
Adult only because age cannot be a minor.
Minor regardless of what age is.
Susie wrote an algorithm with an if-else
statement that assigns 'Fail' to result
if score <60 otherwise 'Pass', which line contains an error?
python
if(score<60):
result = 'Fail'
else:
result = 'Pass'
The colon after (score<60)
should be removed.
No error in this conditional logic; it behaves as intended.
There should be an additional else-if case for scores between 50 and 59.
The <
should be replaced with <=
.
