Linear search:
- Linear search or sequential search is a process of searching for a particular element that is present in the array on by one till the last element until the search element is found.
- The search uses loop that iterates from the beginning till the last element to find the search element.
- The search continues for all the elements present in the array until the last element.
- The search of the target element is made after comparing with the each and every element that is present in the array.

Suppose you wanted to use a linear search on a sorted data set. What would be the average number of comparisons to find a given element? Why?
Run mergesort for huge random arrays and determine empirically, as a function of N (the total of the two subarray sizes for a given merge), the average length of the other subarray when the first subarray exhausts.
When we apply the mergesort on a 12-element array, how many comparisons do we need for the worst case? Ans:

- As an investor, I always check the stock market in order to find good companies to invest in. Recently, I found that the best companies to invest in, are the ones that have largest sum formed by a strictly increasing set of numbers (a set where the next element is always greater than the current element). But before I invest, I need to know the position of the first element of the consecutive increasing numbers. Help me so we can start investing already! Note: If it is already the last element of the row in the array, the next element is the first element of the next row, if there exists a next row. Input 1. Number of rows Description This is the number of rows of the multidimensional array. 2. Number of columns Description This is the number of columns of the multidimensional array. 3.
