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
Answer:
Option A.
Explanation:
In 3D computer graphics, this process determines which elements should not be visible from the desired point of view, and will prevent them from rendering. Thus, objects that lie behind opaque surfaces such as walls or panels, will not be rendered.
A good rendering algorithm helps to optimize the graphic engine because it will load as few elements as possible. Therefore, in larger worlds, the engine will remain at a stable speed and will be more efficient.
Answer:
A. Helps to quickly find information in a document
B. Points readers to specific page numbers
D. Locates specific sections within a document
Answer:
form, place, time, and possession utility
Explanation:
Answer:
You just need to click over the desktop, move to the View, and then change to medium, if its the icon size.
However, if you feel your resolution requires screwing up, then you are required to do the right-click, and again over the Desktop and then move to the settings (screen resolution),
And if you by chance clicked on the magnifier utility, you can CTRL + ALT +DEL and you will also be required to shut the interface.
