Textbook Question
Chapter 9, Problem 4E
Write a function called s to extract a portion of a character string. The function should be called as follows:
s
where S is the character string from which you are extracting the substring, S is an index number into S indicating the first character of the S, c is the number of characters to be extracted from the S string, and r is an array of characters that is to contain the extracted substring.
For example, the call
s
extracts the substring̎ (three characters starting with character number 4) from the string̎ and places the result in r.
Be certain the function inserts a null character at the end of the substring in the result array. Also, have the function check that the requested number of characters does, in fact, exist m the string. If this is not the case, have the function end the substring when it reaches the end of the source string. So, for example, a call such as
s
should just place the string “words” inside the result array, even though 20 characters were requested by the call.

Write a function is ordered that takes an integer array and its size as parameters and returns true if the array elements are ordered in nondecreasing order and returns false if not. For example, integers in {10,0,1,1,5,1009} are ordered in nondecreasing order. On the other hand, integers in {1, 2, 3, 8, 4, 19} are not since 8 > 4
Write a function to find the maximum sum of a subarray within a given array of integers. The subarray should be contiguous, meaning the elements are adjacent to each other in the array.
For example, given the array [-2, 1, -3, 4, -1, 2, 1, -5, 4], the maximum sum of a subarray is 6, which corresponds to the subarray [4, -1, 2, 1].
Write a function named maxSubarraySum that takes an array of integers as input and returns the maximum sum of a subarray.
Note: If all the elements in the array are negative, the function should return 0.
Example:
Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4] Output: 6
Input: [-1, -2, -3, -4] Output: 0
Write the maxSubarraySum function that solves this problem efficiently.
Write a function that takes two int arrays arr1 and arr2, and their size n as parameters. The functionreturns the number of elements that exist in arr1 and arr2 with indexes i1 and i2 respectively such that i1>=i2.(Example: arr1: [ 1,5,2,3,4,0,7] arr2: [0,1,3,7,4,2] then the function returns 3 ( 0,3,7) )

- Write a function named(difference), that accepts an integer one-dimensional array and its size, returns the difference between the largest element and the smallest element. e.g. the array is [1,7,13,22,15,6,4,3,2,9,21] the output is:21arrow_forwardWrite a function that gets an array as a parameter, sorts it in an ascending fashion and returns the number of elements that did not change position in the sort (they were originally in the right position). Use c code int sortASC(int* myArray, int size) if array ={ 2, 3, 1, 0, -1} after calling the function the array should become {-1, 0, 1, 2 , 3 } and the function should return 1 (only one element has not changed place in the array)arrow_forwardWrite a function which takes two arguments: a) A NULL-terminated array of pointer to function, and b) a char *. Each function in the array of function parameter takes the string as its argument and returns a string. The returned strings from the function calls should be copied (create a copy of the string) into an array of pointer to char (NULL terminated!) which YOUR function returns. Make the returned array of pointer EXACTLY the right size (count first, then allocate). Use indices to traverse the array of function pointers and the constructed array of pointers to char.arrow_forward
- Write a function using python: diceSim(D1,D2,trials) that takes as input the number of sides on die 1 (D1) and die2 (D2) and the number of trials. Your function should repeatedly sum pairs of random numbers between 1 and D1 and 1 and D2 and keep track of how many times each sum occurs. The function returns a numpy array with the fraction each sum of rolls occured. Since the numbers are chosen at random, the fractions will differ some from run to run. One run of the function print(p22.diceSim(6,6,10000)) resulted in: [0. 0. 0.0259 0.0615 0.0791 0.1086 0.139 0.1633 0.1385 0.114 0.0833 0.0587 0.0281]arrow_forwardPLease! in c++ Write a function named “getNonNegativeSum” that takes in 4 input parameters: -a pointer to thearray of integers-its size, -the index tostart the sum from -the count of how many numbers from that starting index It will return the sum of all values from the startingindex with the number count of how many. It will add to the sum if the number in the array is positiveand skip all negative values. If there is an error in the indexor not enough numbers to count, it will return -1. For example,int numList[] = {10, 20, -1, 30}; If the starting index is 1 and the count of 3, it will return 50 If the starting index is 2 and the count of 2, it will return 30 If the starting index is -1 and the count of 2, it will return -1 If the starting index is 2and the count of 5, it will return -1.int priceList[] = {10, 20, 30, -1, 40}; If the starting index is 0, and the count is 1, it will return 10 If the starting index is 1, and the count is 3, itwill return 50 If the starting index is 0,…arrow_forwardWrite a function that takes two inputs: - An array of doubles named data. - A scalar double (single number) named threshold.

It should accept three integer arrays: A, B and C, and two integers m and n representing the sizes of the first two arrays. It can be assumed that the size of C is m+n. Arrays A and B contains integers that are already sorted in the ascending order (i.e. increasing order). Your function must combine all the numbers in A and B and store them C in such a way that C is also sorted in the ascending order. Here is an example to clarify the requirements. In this case, the sizes of A and B are 6 and 4 respectively. SAMPLE A : 0 4 5 5 7 9 B: -1 0 3 6 C: -1 0 0 3 4 5 5 6 7 9 Then you have to separate odd and even integers in two separate arrays respectively.arrow_forward
