Binary search needs sorting of arrays and the sorting using data structure link list is very complex. Hence, it is not suitable.

In heap, the most important node is stored at the top position. If it gets deleted, the second most important node replaces it. It is a similar concept as priority queue.

Quick sort technique involves choosing a central element which is used to partition data according to the value. Then, both sets are individually processed by continuous partitioning and the required order is obtained.

Sparse array is an array which assigns a default value to all its element. It may be a constant or null.

a[i] can be written as *(a+i), therefore a[i][j][k][l] can be written as given in the option.

A recursive function uses the stack. 

It follows a simple and easy way to classify a given data set through a certain number of clusters and fixed a priori.

It is the ability of the model to make correct predictions in given noisy data.

It is a collection of machine learning algorithms for data mining task.

It means inappropriate fishing for information or data mining to find misleading relationships to form statistical bias.

It provides software called Darwin, and is data mining tool and incorporates cluster analysis, classification, prediction and association rules.
