Question

(3) There is a function void fnE(int i, int num) that runs in 1000-i steps, regardless of what
num is. Consider the following code snippet:
void fnA(int S[]) {
S.length;
for (int i=0;i<n;i++) {
fnE(i, S[i]);
int n =
}
}
What's the running time in Big-O of fnA as a function of n, which is the length of the array S. You
should assume that it takes constant time to determine the length of an array.
(4) Show that h(n) = 16n2 + 1ln* +0.1n³ is not O(n“).

Answer it is c++ only Chef recorded a video explaining his favorite recipe. However, the size of the video is too large to upload on the internet. He wants to compress the video so that it has the minimum size possible. Chef's video has N frames initially. The value of the th frame is A₁. Chef can do the following type of operation any number of times: • Choose an index i (1 ≤ i ≤ N) such that the value of the ith frame is equal to the value of either of its neighbors and remove the ith frame. Find the minimum number of frames Chef can achieve. Input 1 1 5 output 1

Consider the following function. void printArray(int cards[], int size){ for (int i=0; i<size; i++) {cout << cards[i] << endl; cards[i] = 0; }} It prints the array, but also sets the elements to zero, which seems like a bug for a function that should only print the array. How could we prevent this function from compiling? A) Change i<size to i<=size B) Change void to int C) Insert keyword const before parameter int cards[] D) Change for to while
