Write a program in Ruby language to remove all duplicate elements from the array given below: [21, 22, 23, 24, 21, 22, 22, 23, 25, 26]

1. Write a python program that combines two arrays of the same size one-in-a-row. For instance, if a=[1,2,3,4] and b=[5,6,7,8], the combined array should be [1,5,2,6,3,7,4,8].

write a program by c++ using pointer notation to read the elements of the one dimensional array a[10] then delete the zeros from this array and display the resulted array.

Utilizing c++, write a code to implement the following:Firstly, create(populate) an array (one with unknown size) and determine its(array's) size. Furthermore, the array should then be sorted and its output(prints out) should print each element in the array in order from the last to the 1st index.
