Step by step
Solved in 2 steps with 1 images
- Write the method sum2D() which accepts a two dimensional integer array and returns the sum of all the elements of the array.Write a method sumArray that calculates and returns the sum of a given array of double valuesWrite 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 the method printTail() method that accepts an array of integers and an integer index as parameters and prints all the array elements starting from the index passed. For example if printTail(x,5) is invoked, it should print all the elements of the array x starting at x[5].Write a method SortTheEvens(), that first shifts all the even numbers of an input array to the left side in that array and then sorts all even numbers in that array.Note: You are not allowed to use direct indexing and can only use ptr++ and ptr-- operators. i.e. *(ptr + i) and ptr[i] are not allowed.Do using c++ programming language.Write a method reverse that takes an array as an argument and returns a new array with the elements in reversed order. Do not modify the array. Only edit code in the /* Your code code goes here */ portions.
- 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: 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) {Please don't copy write an algorihm that takes an array of positive integers( it stops reading when it sees a negative number), and the size of the array, and prins the average(type float) of the values.write a method that receives an array and sorts it in an increasing order
- 5. Write a static method largestColumnFirst() that receives as parameter a 2D array numAr,finds the column with the largest sum, and switches it with the first column. For example:6 7 9 4 8 9 7 6 4 83 2 7 4 1 → 7 2 3 4 19 4 5 8 3 5 4 9 8 3Write 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) {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.
