For example, we can store a list of items having the same data-type using the array data structure Anyone with a bit of programming experi-ence will see that these operations are not hard to implement correctly. We can store the data in an array or a linked list and each operation can be implemented by iterating over all the This makes it easier to calculate the position of each element by simply adding an offset to a base value, i.e., the memory location of the first element of the array (generally denoted by the name of the array). We can store the data in an array or a linked list and each operation can be implemented by iterating over all the An array is a collection of homogeneous (same type) data items stored in contiguous memory locations. An array is a collection of items stored at contiguous memory locations.

A data structure should be seen as a logical concept that must address two fundamental concerns. Union-Find Structure Main idea: represent each set by a rooted tree – Every node maintains a link to its parent – A root node is the “representative” of the corresponding set – Example: two sets {x,y,z} and {a,b,c,d} Union-Find Structure 19 After the size of the array is defined at the start, it may not be possible to increase the size of the array without creating a new larger array and copying all values into the new array. create two pointers, each set to the start of the list.
