You are given a matrix C in Matlab, C = [1, 2, 3; 4, 5, 6; 7, 8, 9; 10, 11, 12; 13, 14, 15] What is the result of the following command? >> length (C(3, 2:3))

I need help with this pratice run question. In C++, Implement a Hash Table of size 8191 (= 2^13 - 1) to store integers based on quadratic probing. Design your own hash function that is, in your view, sufficiently non-trivial and efficient to compute. Compare the average number of probes for the following cases:Generate 4000 integer random numbers in the range 0 to 10^6 - 1, and insert them into the hash table. Compute and print the total  number of probes.Repeat step (a) above 10 times, and find the average number of probes over these  10 trials

Write the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result.   - If mystr has at least one instance of adjacent characters being equal, return True   - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error")   if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie")   if not (has_adjacent_repeats("Hanoverr") is True): print("error")

Implement in C Programming 6.11.2: Modify an array parameter. Write a function SwapArrayEnds() that swaps the first and last elements of the function's array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}. #include <stdio.h> /* Your solution goes here  */ int main(void) {   const int SORT_ARR_SIZE = 4;   int sortArray[SORT_ARR_SIZE];   int i;   int userNum;    for (i = 0; i < SORT_ARR_SIZE; ++i) {      scanf("%d", &sortArray[i]);   }    SwapArrayEnds(sortArray, SORT_ARR_SIZE);    for (i = 0; i < SORT_ARR_SIZE; ++i) {      printf("%d ", sortArray[i]);   }   printf("\n");    return 0;}
