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:
Command Operations
Explanation:
Space Operation specialist requires special training for aircraft and its operations along with satellite controls. Initially when a graduate joins the training he is required to understand command operations of aircraft. He can then use his skills to learn command operation of spacecraft and then will be promoted to learn satellite controls.
Answer:
C. forums
Explanation:
Forums are internet sites where users can meet to discuss different topics through the use of messages thereby forming chat rooms. An internet forum can be in form of a question and answer site. Most websites have internet forums where users can meet and discuss or ask questions. Sometimes there may be moderators that ensure that the posted messages are acceptable based on guidelines.
Answer:
Explanation:
The following code is written in Python. It is a function called guessMyNumber and like requested creates a random number and saves it to secretNumber. Then it continuously asks the user for their guess and compares it to the secret number. If the guess is correct it exits the loop otherwise it will continue to ask for a new guess.
import random
def guessMyNumber():
secretNumber = random.randint(1, 10)
print(secretNumber)
while True:
guess = input("Enter your guess: ")
guess = int(guess)
if (guess == secretNumber):
print("Congratulations you guessed correctly")
