/**
* Build a sparse array from the given indices and values with
* specific length.
*
* Arguments:
* value Array of values
* index Array of indices
* length Length of the above arrays
*
* Returns:
* A sparse array.
*
* If a sparse array node has { value = 1000, index = 2 }, then that means that
* the index "2" caries the value "1000". This is meant to convey an array of 1000
* "2s", but instead of creating 1000 nodes in your linked list, you only create
* 1 node, and that note conceptually has 1000 "copies" of it. Hence
* each node in a sparse array has a "value" in addition to its "index".
*
* Note that an index can never carry the value of "0", because this would not make
* any sense; however, negative values are fine. A negative value may seem odd
* at first blush; however, this is like substraction, and makes sense for certain
* cases.
*
* You need to insert nodes in ascending order by index.
* See the notes to "List_insert_ascend"
