<p>The general strategy for hashing integer keys is to use the modulo operation, i.e., Key mod TableSize.</p> Signup and view all the answers

<p>The problem is that the number of possible keys is much larger than the space available in the table, and a simple hash function may not distribute the keys evenly.</p> Signup and view all the answers

<p>The function is called a hash function because it 'makes a hash' of its inputs, meaning it takes the input and transforms it into a seemingly random value.</p> Signup and view all the answers

<p>When the code reaches the end of the <code>while</code> loop, it means the correct position for the new node has been found, and the new node is created and attached to the parent node.</p> Signup and view all the answers
