Answer:
They provide us with ways to communicate, display, and work with information more quickly and accurately.
Explanation:
Productivity programs helps in the provision of information and they also help in increasing productivity by making work less stressful and unambiguous. Examples of productivity programs include design programs and spreadsheet tools.
These programs also create an avenue for providing us with ways to communicate, display and work with information more quickly and accurately.
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:
The Web is the system of web pages and sites that uses the Internet to pass the files across. It was developed in the late 1980’s by Tim Berners-Lee, and you <em>need a Web Browser to access it</em>. This could either be in a PC, a mobile phone or one of the new iPods.
Explanation:
I guess you could look at it as just one of many services that use the Internet – other services include e-mail, internet telephony and peer-to-peer file transfers. Hope this helps ^-^
