Write a recursive function double recSum(double array[], int count); that takes an int argument and returns the sum of count array entries. C++, please explain how the code works.

Write a recursive function that accepts a number and returns its factorial. b. Write a recursive function that accepts an array, its size and the index of the initial element as arguments. The function fills the array with the elements of the following sequence: n1 = 3, nk+1 = nk+35 c. Write an iterative and a recursive versions of the binary search. In C++ coding

1-Write a C++ program to delete duplicate elements from array. How to remove duplicateelements from array in C++ programming. After performing delete operation the arrayshould only contain unique integer value. Logic to delete duplicate elements from array.ExampleInputInput array elements: 10, 20, 10, 1, 100, 10, 2, 1, 5, 10OutputAfter removing all duplicate elementsElements of array are: 10, 20, 1, 100, 2, 5

Please use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 3. Define a class which stores up to 10 integer values in an array.  The class should also define the following 4 public methods:       setNumber – accepts an integer value to store in the array.  The value is stored in the next available element of the array (first call to the method stores the value in element 0 with the second call storing the value in element 1.) The method returns true if there is room in the array and the integer was successfully stored.  Returns false otherwise.        clear – removes all values from the array so that the array can be reused.     displayNumbers – displays the values currently stored in the array.     getStats – determines the largest, smallest, and average of the values currently stored in the array.  These values are returned to the caller via reference parameters. All methods should produce correct results regardless of the order in which…

I need help with this in C++: Write a pair of functions countEven(int *, int) and countOdd(int *, int) which receive an integer array and its size, and returns the count of even or odd numbers in the array.

in c++ write a code to return the value of fake coin, the fake coin is The different element of the value in the array ،and need for way solution using 1) brute force approaches 2) divide and conquer 3) decrease and conquer 4) transform and conquer and write the time of each one and what the best time of them.   in c++ write a code to return the value of fake coin, the fake coin is The different element of the value in the array and be less value (minimum) , need four way solution using 1) brute force approaches   2)divide and conquer   3)decrease and conquer 4) transform and conquer   and write the time of each one and what the best time of them.
