Answer:

see down -

Explanation:

a ) Computer is an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.

b ) A reason is that people wanted better and efficient calculating devices. This started from the abacus to ENIAC and UNIVAC. Also, modern computers work on the principle of input-process-output and George Boole's logic.

c ) A weakness of a computer is that it isn't so open-minded like human brains. They can't make logical answers and created to give a specific set of answers. They also can't read real human emotions.

d ) Full form of CCTV is Closed Circuit Television. Full form of MRI is Magnetic Resonance Imaging.

Give 5 stars and Brainliest if I am correct on all answers.

Elis [28]

Answer:

(a) What is the best case time complexity of the algorithm (assuming n > 1)?

Answer: O(1)

(b) What is the worst case time complexity of the algorithm?

Answer: O(n^4)

Explanation:

(a) In the best case, the if condition will be true, the program will only run once and return so complexity of the algorithm is O(1) .

(b) In the worst case, the program will run n^4 times so complexity of the algorithm is O(n^4).

A domestic air carrier airplane lands at an intermediate airport at 1815Z. The latest time it may depart without a specific auth
serious [3.7K]

Answer:

A domestic air carrier airplane lands at an intermediate airport at 1815Z. The latest time it may depart without a specific authorization from an aircraft dispatcher is <u>1915Z (1 hour)</u>.

Explanation:

Under the domestic operations, an airplane landed on intermediate airport can remain their for not more than one hour so the time would me 1 hour.

Here the time represented by 1815Z and 1915Z is in Zulu Time Zone as depicted from letter "Z". The first two digits represent the hour (0-24) and the next two represent the minutes (0-59).

  • Here the landing time is 6:15 pm while departing time is after one hour that is 7:15 pm (1915Z).

i hope it will help you.

Develop a CPP program to test is an array conforms heap ordered binary tree. This program read data from cin (console) and gives
mafiozo [28]

Answer:

Following are the code to this question:

#include<iostream>//import header file

using namespace std;

int main()//defining main method

{

int ar[7];//defining 1_D array that stores value      

int i,x=0,l1=1,j; //defining integer variable

for(i=0;i<7;i++)//defining for loop for input value from user ends  

{

cout<<"Enter a Number: ";//print message

cin>>ar[i];//input value in array

if(l1<=2 && i>0)//using if block that checks the array values  

{

x++;//increment the value of x by 1  

}

if(l1>2 && i>0)//using if block that checks the array values  

{

l1=l1-2;//using l1 variable that decrases the l1 value by 2  

}

j=i-x;//using j variable that holds the index of the root of the subtree

if(i>0 && ar[j]>ar[i])// use if block that checks heap condition  

{

l1++; //increment the value of l1 variable

}

if(i>0 && ar[j]<ar[i])// using the if block that violate the heap rule  

{

cout<<ar[i]<<" "<<"Violate the heap";//print message with value

break;//using break keyword  

}

}

return 0;

}

Output:

1)

Enter a Number: -15

Enter a Number: -5

-5 Violate the heap

2)

Enter a Number: 45

Enter a Number: 0

Enter a Number: 55

55 Violate the heap

Explanation:

  • In the above-given C++ language code, an array "ar" and other integer variables " i,x,l1, j" is declared, in which "i" variable used in the loop for input values from the user end.
  • In this loop two, if block is defined, that checks the array values and in the first, if the block it will increment the value of x, and in the second if the block, it will decrease the l1 value by 2.
  • In the next step, j variable is used that is the index of the root of the subtree. In the next step, another if block is used, that checks heap condition, that increment the value of l1 variable. In the, if block it violate the heap rule and print its values.

Identify a logical operation (along
tankabanditka [31]

Answer: Provided in the explanation section

Explanation:

The Question says;

Identify a logical operation (along

with a corresponding mask) that, when

applied to an input string of 8 bits,

produces an output string of all 0s if and

only if the input string is 10000001.​

The Answer (Explanation):

XOR, exclusive OR only gives 1 when both the bits are different.

So, if we want to have all 0s, and the for input only 10000001, then we have only one operation which satisfies this condition - XOR 10000001. AND

with 00000000 would also give 0,

but it would give 0 with all the inputs, not just 10000001.

Cheers i hope this helped !!
