Explanation:
The answer is as mentioned above. And these are important words from subject Professional Communication. And like when we talk of an exchange of information, we mean communication. And similarly, other words means as being mentioned above.  
 
        
             
        
        
        
<span>The correct answer here is Hallucinogen.
Technically all drugs one way or another distort the perception of reality and thought processes but hallucinogens are especially potent in that regard. Hallucinogens are those agents that can cause, among other things, hallucinations and changes in consciousness, emotions and thoughts. LSD is maybe the most known representative of the hallucinogens. </span>
        
             
        
        
        
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
 
        
             
        
        
        
The managed service should you use if you want to do a lift and shift of an existing Hadoop cluster without having to rewrite your Spark code is f G. Cloud's.
<h3>What is Lift and shift Hadoop clusters?</h3>
This is one where a person can migrate their existing Hadoop and Spark deployment so that they can use G. Cloud without  having to engage in re-architecting. 
The managed service should you use if you want to do a lift and shift of an existing Hadoop cluster without having to rewrite your Spark code is f G. Cloud's as it is advantage fast and flexible way to put together infrastructure as a service and others.
