Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

Language/Type:
Java arrays
Write a method named collapse that accepts an array of integers as a
parameter and returns a new array where each pair of integers from the
original array has been replaced by the sum of that pair. For example, if an
array called a stores {7, 2, 8, 9, 4, 13, 7, 1, 9, 10), then the call
of collapse (a) should return a new array containing
{9, 17, 17, 8, 19). The first pair from the original list is collapsed into
9 (7+2), the second pair is collapsed into 17 (8 + 9), and so on.
If the list stores an odd number of elements, the final element is not
collapsed. For example, if the array had been {1, 2, 3, 4, 5}, then the
call would return {3, 7, 5}. Your method should not change the array
that is passed as a parameter.

Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).
