I believe the answer to be A) because distance with the time it took to to reach the distance would determine how speed is to be calculated.

Consider the following method, remDups, which is intended to remove duplicate consecutive elements from nums, an ArrayList of in

MAXImum [283]

Answer:

B. {1, 2, 2, 3, 3, 4, 5}

Explanation:

Given

The above code segment

Required

Determine which list does not work

The list that didn't work is $B.\ \{1, 2, 2, 3, 3, 4, 5\}$

Considering options (A) to (E), we notice that only list B has consecutive duplicate numbers i.e. 2,2 and 3,3

All other list do not have consecutive duplicate numbers

Option B can be represented as:

$nums[0] = 1$

$nums[1] = 2$

$nums[2] = 2$

$nums[3] = 3$

$nums[4] = 3$

$nums[5] = 4$

$nums[6] = 5$

if (nums.get(j).equals(nums.get(j + 1)))

The above if condition checks for duplicate numbers.

In (B), when the elements at index 1 and 2 (i.e. 2 and 2) are compared, one of the 2's is removed and the Arraylist becomes:

$nums[0] = 1$

$nums[1] = 2$

$nums[2] = 3$

$nums[3] = 3$

$nums[4] = 4$

$nums[5] = 5$

The next comparison is: index 3 and 4. Meaning that comparison of index 2 and 3 has been skipped.

<em>This is so because of the way the if statement is constructed.</em>

(iii) If 1 GB = 2x<br>then what is the<br>value of x?

frez [133]

Since a Gigabyte is made of Megabytes, 500 Megabytes times 2, 2(500MB), is equal to one Gigabyte. (1000MB)
UNLESS, it wants the Windows way of storage, because one Gigabyte in Windows terms is actually 1024 megabytes... then it’d be 2(512MB) because 512MB and 512MB equals one windows storage gigabyte.

Don wishes to swap the values of the variables x and y in his program. He adds a line of code which sets the value of x to the v

12345 [234]

Answer:

The correct answer is (c): The value of both x and y will be set to the original value of y.

Explanation:

Let suppose, we assign some value to variable x and to variable y i.e.

var x=10

vary y=15

Then Don adds a line of code which set the value of x to value of y i.e.

x=y

here it is mean that value of x become 15.

So after this line the value of x is 15 and y is also 15

Then he also added a line of code which set the value of y to value of x. i.e.

y=x

By adding this line of code, the value of y is 15 because x is equal to 15.

Therefore, the value of both x and y will be set to the original value of y.

Why other option are not correct

a. After swapping the value of both variable it is impossible that both variable retain original value in it.

b. this option is only true if in this first line he set the value of y to value of x and in the second line set the value of x to value of y.

d. When you swap two values, there is need of third variable for swapping, when you will swap the value only between two variable, only one variable value will be retained and intended swapping will not be performed
