Answer:

The answer to this question is true.

Explanation:

Data Dictionary is the component that stores metadata (data about data). It is part of the Database Management System(DBMS). The data dictionary is used to contain information such as what is the database and who will be allowed to access it and where is it stored etc. When we develop a program it uses the data model and data dictionary. That is used to understand what data item fits in the structure and what value will it contain.  So the answer to this question is true.

which one of the following will reach every element in the array a? 1. for(int i = 0; i &lt;= a.length; i++) 2. for(int i = 0; i
andrey2020 [161]

Answer:

You can simplify the problem down by recognizing that you just need to keep track of the integers you've seen in array that your given. You also need to account for edge cases for when the array is empty or the value you get would be greater than your max allowed value. Finally, you need to ensure O(n) complexity, you can't keep looping for every value you come across. This is where the boolean array comes in handy. See below -

public static int solution(int[] A)

{

int min = 1;

int max = 100000;

boolean[] vals = new boolean[max+1];

if(A.length == 0)

return min;

//mark the vals array with the integers we have seen in the A[]

for(int i = 0; i < A.length; i++)

{

if(A[i] < max + 1)

vals[A[i]] = true;

}

//start at our min val and loop until we come across a value we have not seen in A[]

for (int i = 1; i < max; i++)

{

if(vals[i] && min == i)

min++;

else if(!vals[i])

break;

}

if(min > max)

return max;

return min;

}

If a menu item requires additional information from the user, the Windows standard is to place a(n) ____ at the end of the capti
elena-s [515]

Answer:

elipses

Explanation:

According to my research on information technology, I can say that based on the information provided within the question the windows standard in this situation would be to place an ellipses at the end of the caption. This is because in the English language an ellipses (...)  usually indicates an intentional omission of a word or sentence, which in computer science is used to give the user an indication that it requires further user input.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
