- [Fish Tank] You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j. When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size. The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…public static int Ack(int m, int n) { if (m == 0) { return n + 1; } else if (n == 0) { return Ack (m } else { } } return Ack (m - - 1, 1); 1, Ack (m, n- What is the return value of this function for a. Ack(0,0) b. Ack(0,3) c. Ack(0,6) Can you use the above three samples and come up with a formula for Ack(0,n)? 1));Consider the following function: public void bSearch(int[] A, int value, int start, int end) { if (end value) { return bSearch(A, value, start, mid); } else if (value > A[mid]) { return bSearch(A, value, mid+1, end); } else { return mid; } } The mutation program P' changes the part as shown below. } else if (value > A[mid]) { return bSearch(A, value, mid+2, end); } else { return mid; } A test input is given t1: {A = [2, 3, 5, 7, 10, 11], value = 6, start=0, end=5}. Which statement below best describes the mutant with regards to the test input? O a. t1 resolves mutant P O b. The mutant P' with regards to test input t1 is live.
- Create a program that accepts an integer N, and pass it to the function generatePattern. generatePattern() function which has the following description: Return type - void Parameter - integer n This function prints a right triangular pattern of letter 'T' based on the value of n. The top of the triangle starts with 1 and increments by one down on the next line until the integer n. For each row of in printing the right triangle, print "T" for n times. In the main function, call the generatePattern() function. Input 1. One line containing an integer Output Enter N: 4 T TT TTT TTTTWhat is the value of sum?int w = 5;int sum = 0;for (int r = 1; r <= w; r++)for (int s = r; s <= w; s++)sum = sum + s;int getMax(int arr[], int n) { intmx=arr[0]; for (inti=1; i<n; i++) if (arr[i] >mx) mx=arr[i]; returnmx; } Can u give me the code for this one as well....this is the first function and countsort is the second
- 1. Given the following function: int Fn (int N) { } if (N == 0) return 2; else return N + Fn (N/3); a) What type of function is this, Iterative or Recursive? Give justification. b) Given N = 17, what will be the output from this function? Show your work.Write in C++ Alice is trying to monitor how much time she spends studying per week. She going through her logs, and wants to figure out which week she studied the least, her total time spent studying, and her average time spent studying per week. To help Alice work towards this goal, write three functions: min(), total(), and average(). All three functions take two parameters: an array of doubles and the number of elements in the array. Then, they make the following computations: min() - returns the minimum value in the array sum() - returns the sum of all the values in the array average() - returns the average of all the values in the array You may assume that the array will be non-empty. Function specifications: Function 1: Finding the minimum hours studied Name: min() Parameters (Your function should accept these parameters IN THIS ORDER): arr double: The input array containing Alice's study hours per week arr_size int: The number of elements stored in the array Return Value:…By how much is the time for INT operations reduced if the total time is reduced by 20%?
- mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.what could go wrong with the function show on the right? (tip: syntax error is not the answer) void goo(unsigned int n) { if (n==0) return; cout << n; goo(n-2); }The following is a implementation of the Ackermann function: public static long Ackermann(int m, int n){ 0) return n + 1; if (m == else if (n == return Ackermann(m 1, 1); else return Ackermann(m 1, Ackermann(m, n - 1));
