Step 1
Algorithm for N-Queens problem using backtracking approach: Step 1: Initialize an empty chessboard of size N x N. Step 2: Start with the first row and place a queen in the first column. Step 3: Move to the next row and place a queen in the first column. Step 4: Show more…

Develop and write pseudo only one code for an algorithm that contain following : Find the maximum number from an array of size n. Find the minimum number from the same array of size n. Find the difference between the largest and the smallest elements of the array. Count that how many elements of the array are bigger than the difference computed in the previous step and output that number. And Then Analyze your algorithm and find its complexity class

The complexity of a computer algorithm is the number of operations or steps the algorithm needs to complete its task assuming there are $n$ pieces of input (for example, the number of steps needed to put $n$ numbers in ascending order). Four algorithms for doing the same task have complexities of $\mathrm{A}: n^{3 / 2}, \mathrm{B}: n \log _{2} n, \mathrm{C}: n\left(\log _{2} n\right)^{2},$ and $\mathrm{D}: \sqrt{n} \log _{2} n .$ Rank the algorithms in order of increasing efficiency for large values of $n$ Graph the complexities as they vary with $n$ and comment on your observations.
