Introduction To Algorithm
The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results.
Advantages of Algorithms:
- It is easy to understand.
- Algorithm is a step-wise representation of a solution to a given problem.
- In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program.

Forming a Magic Square – Hacker Rank Solution
Problem:
We define a magic square to be an matrix of distinct positive integers from to where the sum of any row, column, or diagonal of length is always equal to the same number: the magic constant.
You will be given a matrix of integers in the inclusive range . We can convert any digit to any other digit in the range at cost of . Given , convert it into a magic square at minimal cost. Print this cost on a new line.
Note: The resulting magic square must contain distinct integers in the inclusive range .
Example
$s = [[5, 3, 4], [1, 5, 8], [6, 4, 2]]
The matrix looks like this:
5 3 4 1 5 8 6 4 2
We can convert it to the following magic square:
8 3 4 1 5 9 6 7 2
This took three replacements at a cost of .
Function Description
Complete the formingMagicSquare function in the editor below.
formingMagicSquare has the following parameter(s):
- int s[3][3]: a array of integers
Returns
- int: the minimal total cost of converting the input square to a magic square
Input Format
Each of the lines contains three space-separated integers of row .
Constraints
