Objective Today, we're learning about the  Array  data structure. Check out the  Tutorial  tab for learning materials and an instructional video! Task Given an array,  , of   integers, print  's elements in  reverse  order as a single line of space-separated numbers. Input Format The first line contains an integer,   (the size of our array). The second line contains   space-separated integers describing array  's elements. Constraints , where   is the   integer in the array. Output Format Print the elements of array   in reverse order as a single line of space-separated numbers.

Objective Today we're expanding our knowledge of Strings and combining it with what we've already learned about loops. Check out the  Tutorial  tab for learning materials and an instructional video! Task Given a string,  , of length   that is indexed from   to  , print its  even-indexed  and  odd-indexed  characters as   space-separated strings on a single line (see the  Sample  below for more detail). Note:    is considered to be an  even  index. Input Format The first line contains an integer,   (the number of test cases). Each line   of the   subsequent lines contain a String,  . Constraints Output Format For each String   (where  ), print  's  even-indexed  characters, followed by a space, followed by  's  odd-indexed  characters. Sample Input 2 Hac...
