Answer:
This article discusses different ways to reverse a string in Java with examples.
In conclusion there are many different data structures. Each data structure has strengths and weaknesses which affect performance depending on the task. Today, we explored two data structures: arrays and linked lists. Arrays allow random access and require less memory per element (do not need space for pointers) while lacking efficiency for insertion/deletion operations and memory allocation. On the contrary, linked lists are dynamic and have faster insertion/deletion time complexities. However, linked list have a slower search time and pointers require additional memory per element in the list. Figure 10 below summarizes the strength and weakness of arrays and linked lists.
Answer:
C (Window/Orphan control)
Explanation:
An "orphan" in formatting is a single line of text that is left alone/separated from the rest of the paragraph. Orphan control prevents this from happening by keeping lines together.
Corrected or Complet Question
The ____ operator executes one of two expressions based on the results of a conditional expression.
a. .
b. ( )
c. ,
d. ?:
Answer:
(d) ? :
Explanation:
The ternary operator (? :) is an operator that executes one out of two expressions based on the results of a conditional expression. It is a faster or shorthand way of writing an if ... else statement. The operator checks the conditional expression and depending on whether it is true or false, one of its two statements will be executed. For example:
String correct = (4 < 5) ? "yes" : "no" ;
In the code above,
i. the conditional statement is (4 < 5) and this will be tested for to return true or false.
ii. the first expression (the one after the ?) is "yes" which will be executed if the conditional statement returns true.
iii. and the second expression (the one after the : ) is "no" which will be executed if the conditional statement returns false.
Therefore, since the conditional expression returns true for 4 < 5, the first expression will be executed. i.e "yes". This means that the String variable <em>correct </em> will have a value of "yes".
