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>

Answer:

The answer is "Using the DoD 5220.22-M method and Degauss media with a magnet".

Explanation:

The "DoD Standard" is a term used during the data sanitizing industry and refers to DoD 5220.22-M. The simplest ways are being used to help eliminate the previously stored data, by deleting hard disc storage facilities with the same data wherever that used a sequence of all zeros.

The sparging eliminates statistics to entirely delete the gravitational flux from electronic media. Hard drives as well as other data storage devices, for example, computer tapes, retain magnetic data. It could no longer be seen as storage after a disk is degaussed.
