Answer:
a. x^<i>(j)
Explanation:
The solution has been explained in the question; however, I will provide further explanation.
The sequence to access a word is:
Training example --> Word
In other words, you first access the training example, before you gain access to the word being searched for.
Rewrite the following:
Training example --> Word
as:
ith training example --> jth word
Hence, the representation is:

Answer: In java the symbol "+" operator is used to perform string concatenation.
Explanation:
String concatenation refers to joining of two strings. So in java + is used to join strings which works provided one of the operands must be a String variable. Then it works by converting the other variable to String variable and joins the second operand to the end of the first operand.
An example of String concatenation is as follows:
int age = 10;
System.out.println("The boys age is " + age);
Output:
The boys age is 10.
here, the age is integer variable but as the phrase "The boys age is" is a String variable so it converts the age to String variable and joins both the Strings.
Answer:
b. selection sort
b. 8 11 17 30 20 25
Explanation:
The options above are the correct answers to the given questions.
Selection sort is a simple comparison-based sorting algorithm.
selection sort. (algorithm) Definition: A sort algorithm that repeatedly searches remaining items to find the least one and moves it to its final location. The run time is Θ(n²), where n is the number of elements. The number of swaps is O(n).
It is this sorting algorithm that will best ne suitable in the given event.
