Answer:

punched-card machine

Explanation:

We know this as the punched-card machine, and it is also known as the Hollerith cards or the IBM cards. At that time, and through this technology, we used to punch a hole with hand or with the machine, and each hole used to represent the data and the instruction. And these were widely used for inputting the data in the early computers.

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>

Which expression correctly determines that String s1 comes before String s2 in lexicographical order

Assoli18 [71]

Options :

A.) s1 < s2

B.) s1 <= s2

C.) s1.compareTo(s2) == −1

D.) s2.compareTo(s1) < 0

E.) s1.compareTo(s2) < 0

Answer: E.) s1.compareTo(s2) < 0

Explanation: Lexicographical ordering simply means the arrangement of strings based on the how the alphabets or letters of the strings appear. It could also be explained as the dictionary ordering principle of words based on the arrangement of the alphabets. In making lexicographical comparison between strings, the compareTo () method may be employed using the format below.

If first string = s1 ; second string = s2

To compare s1 with s2, the format is ;

s1.compareTo(s2) ;

If s1 comes first, that is, before s2, the method returns a negative value, that is a value less than 0 '< 0', which is the case in the question above.

If s2 comes first, that is, before s1, the method returns a positive value, that is a value greater than 0 '> 0'.

If both are s1 and s2 are the same, the output will be 0.
