Answer #1

Answer-

Difference between time efficiency and space efficiency-

Sr.No. Time efficiency Space efficiency
1. It means the time required
for an algorithm to execute.		 It means the memory
required for an algorithm to execute.
2. It is also called time complexity. It is also called space complexity.
3. The time efficiency is expressed by asymptotic notations i.e.Big O - O(n),Big Theta - Θ(n) and Big Omega - Ω(n) Space efficiency is generally expressed by Big
O- (O(n)) notation.
4. The time efficiency is analyzed in three ways i.e.worst case,average case and best case. The Space efficiency is analyzed in terms of instruction space,data space and run-time stack space.

In class, we have studied the linear time algorithm for selection. In that algorithm, we have used groups of size 5. Suppose we are using groups of size 13. • derive the corresponding recurrence formula. • What is the corresponding time complexity of the algorithm? I found the reccurance relation to be T(n)=O(n)+T(n/13)+T(19n/26), but I am having trouble finding the time complexity. Also I really want to learn this, so a detailed response would be nice. I believe it is...
