7. What is the worst-case running time complexity of an algorithm with the recurrence relation T(N) = 2T(N/4) + O(N2)? Hint: Use the Master Theorem.
Worst-case complexity of quicksort is similar to the every-case complexity of exchange sort. Average-case time complexity of quicksort is as good as worst-case time complexity of mergesort. Similar to quicksort, mergesort uses a pivot to partition the input array. Select one: True False
FOR ALGORITHM A WORST CASE TIME COMPLEXITY IS DESCRIBED BY RECURRENCE FORMULA T(n)= n/ T (n )thi T (c)=1 if c < 100 FOR ALGORITHM B WORST TIME COMPLEXITY IS DESCRIBED BY RECURRENCE FORMULA T(n) = 2T (2/2) + n/logn ; (c) = 1 fc 2100 WHICH ALGORITHM IS ASYMPTOTICALLY FASTER? WHY?
Which big-O expression best characterizes the worst case time complexity of the following code? public static int foo(int N) ( int count = 0; int i1; while (i <N) C for (int j = 1; j < N; j=j+2) { count++ i=i+2; return count; A. O(log log N) B. O(log N2) C. O(N log N) D. O(N2)
In C++ How do you demo that selection sort has O(N2) complexity? Meaning of the O(N2). If you have N=1000 input values the selection sort need roughly 1000000 steps. What is the meaning of thee ‘step’ here? One ALU comparison, one swapping of values, or one calculation step on one value of the array. What is the total number of steps for selection sort? Let me use an example N=5, to help me think 4+1-__ 3+1-__ 2+1-__ 1+1-__ F(N)=__________________________ This...

Determine the worst-case complexity of the algorithm in terms of n. // search a key in an array a [1..n] of length n for(int k = 1; k <= n; k++) if(a[k] == key) then return k; return -1; // meaning key not found
