Step by step
Solved in 2 steps
- Write method findZero, as started below. findZero should return the index of the first element of array A that contains the value zero, starting from position 0 up through position pos. If no element of A from position 0 to position pos contains the value zero, then findZero should return –1. For example:(in java) Array (A) Position (pos) Value returned by findZero(A, pos) 1 0 2 5 6 0 -1 1 0 2 5 6 1 1 1 0 2 5 6 2 1 1 0 2 0 6 2 1 1 0 2 0 6 4 1 1 2 3 4 5 4 -1 Complete method findZero below. Assume that it is called only with values that satisfy its assumptions as stated below. // Description: Returns smallest index k // such that (0 <= k <= pos) and (A[k] == 0) // Assumptions: 0 <= pos < A.length public int findZero(int[] A, int pos) {Consider the array A with elements:Suppose A is declared as an integer array with the starting address at 2000. What is the address of the second element i.e. the address of the cell holding integer 3 in the array?Write a program that first reads an integer for the array size, then reads numbers intothe array, and finally outputs how many numbers have values that are greater than theaverage. For practice reasons, try not to use the index notation of arrays (e.g. myarray[i])at all. Use pointers instead.
- Implement the function below. void swap(int pos1, int pos2){} Initial code to be completed: class ArrayList : public List { int* array; int index; int capacity; void dyn_all_add(){ int cap = ceil(capacity * 1.5); array = (int*)realloc(array,cap * sizeof(int)); capacity = cap; } void dyn_all_rem(){ int cap = capacity - (capacity/3); array = (int*)realloc(array,cap * sizeof(int)); capacity = cap; } public: // CONSTRUCTOR ArrayList() { capacity = 4; array = (int*)malloc(capacity); index = 0; } int add(int num) { if (index == capacity){ dyn_all_add(); } *(array + index) = num; index++; return index; } int get(int pos){ if (pos-1 < index){ return *(array + pos-1); } return -1; } int size(){ return index; }…Given an array as follows5 4 9 10 2 8 1 3 7 6 Suppose we partition this array using quicksort's partition function and using 5 for the pivot. A) Draw the resulting array after the partition finishes.B) The following is an array which has just been partitioned by the first step of quicksort:3 0 2 4 5 8 7 6 9Give all the elements that could be the pivot? (There may be more than one possibility!) PLEASE HELP WITH PART A AND B AND SHOW WORK!!In file as c++ Using dynamic arrays, implement a polynomial class with polynomial addition,subtraction, and multiplication. Discussion: A variable in a polynomial does nothing but act as a placeholder forthe coefficients. Hence, the only interesting thing about polynomials is the arrayof coefficients and the corresponding exponent. Think about the polynomialx*x*x + x + 1Where is the term in x*x ? One simple way to implement the polynomial class is touse an array of doubles to store the coefficients. The index of the array is theexponent of the corresponding term. If a term is missing, then it simply has a zerocoefficient.There are techniques for representing polynomials of high degree with many missingterms. These use so-called sparse matrix techniques. Unless you already knowthese techniques, or learn very quickly, do not use these techniques.Provide a default constructor, a copy constructor, and a parameterized constructorthat enables an arbitrary polynomial to be constructed.Supply…
- Write a Python application to load strings into a dynamic array. Allow the user to add and delete pieces? Explain each line?Talk about the difference of accessing elements in an array VS access the memory address of an array What will happen with the following code: 1: cout << array<<endl; 2: cout << array[0] << endl; Does C++ support Index Out of bound Checking? If so, please explain how that works, if not, explain what will happen if Index Out of bound happens.Write a Java class that creates a 3x4 array of 12 random ints between 0 and 100. Write a method to return the sum of the elements in the last column of each row in the two-dimensional array.
- Write a program to ask the user for the number of arrays he wants to maintain and then populate eacharray by taking elements from the user. Merge all these arrays in another array and finally remove duplicateelements from the merged array.Write a java method called SearchKey that return the indices of the first and the last occurences of an element k in an array.The function should Return [-1,1] in case the element was not foundWrite a program to take input of 100 integers in a dynamically allocated array using malloc() function, then find the average of numbers that are in between 20 and 80. For example if an array contains [10, 40, 15, 20, 30, 90] then the average will be (40+20+30) / 3 = 30.
