A folder can include everything from documents and music, to applications [like Word or Excel or your favorite browser]. But computer folders can also contain other folders, lots of them, and those sub-folders can contain folders of their own. This is the called folder tree. The trunk of the tree is the Desktop. Then there are several folders like Recycle Bin, Control Panel,..The most important branch is the one called ‘Libraries’. Here are the Photos, Music, Videos,...

You are given a list of n positive integers a1, a2, . . . an and a positive integer t. Use dynamic programming to design an algo
Anna11 [10]

Answer:

See explaination for the program code

Explanation:

The code below

Pseudo-code:

//each item ai is used at most once

isSubsetSum(A[],n,t)//takes array of items of size n, and sum t

{

boolean subset[n+1][t+1];//creating a boolean mtraix

for i=1 to n+1

subset[i][1] = true; //initially setting all first column values as true

for i = 2 to t+1

subset[1][i] = false; //initialy setting all first row values as false

for i=2 to n

{

for j=2 to t

{

if(j<A[i-1])

subset[i][j] = subset[i-1][j];

if (j >= A[i-1])

subset[i][j] = subset[i-1][j] ||

subset[i - 1][j-set[i-1]];

}

}

//returns true if there is a subset with given sum t

//other wise returns false

return subset[n][t];

}

Recurrence relation:

T(n) =T(n-1)+ t//here t is runtime of inner loop, and innner loop will run n times

T(1)=1

solving recurrence:

T(n)=T(n-1)+t

T(n)=T(n-2)+t+t

T(n)=T(n-2)+2t

T(n)=T(n-3)+3t

,,

,

T(n)=T(n-n-1)+(n-1)t

T(n)=T(1)+(n-1)t

T(n)=1+(n-1)t = O(nt)

//so complexity is :O(nt)//where n is number of element, t is given sum

Which line of code will print I like to code on the screen? print("I like to code") print(I like to code) print("I LIKE TO CODE"
Bad White [126]

Answer:

print("I like to code")

Explanation:

In the Programming Languages, print() function is used to print any string, display any output or both at the same time as well as we can print it one by one. We can also print addition, subtraction, multiplication and other problems directly without saving it in other objects or variables.

In the above statement, the correct method of printing any string is to write that string inside the parameter with a double-quote.

The second option is incorrect because in it double-quote is not used.

The third option is incorrect because the following sequence is not correct.

All of the following can cause a fatal execution-time error except: Group of answer choices Dereferencing a pointer that has not
7nadin3 [17]

Answer: Dereferencing a variable that is not a pointer

Explanation:

The execution time also refered to as the CPU time pertaining to a given task is the time that is used by the system to execute a task.

Some of the reasons for a fatal execution-time error include:

• Dereferencing a pointer that has not been initialized properly

• Dereferencing a null pointer

• Dereferencing a pointer that has not been assigned to point to a specific address.

It should be noted that dereferencing a variable that is not a pointer doesn't cause a fatal execution-time error.
