Step by Step solution about How to resolve the algorithm Stem-and-leaf plot step by step in the C# programming language

The provided code is a C# program that generates a stem-and-leaf plot for a given array of integers, it takes an array of integers as input and displays a stem-and-leaf plot, which is a graphical representation of the distribution of data.

Here's a detailed explanation of the code:

1. The program starts by defining a constant string data that contains a space-separated list of integers.

2. The string data is split into an array of integers using the Split and Select methods.

3. The StemAndLeafPlot method is called to generate the stem-and-leaf plot for the array of integers.

4. Inside the StemAndLeafPlot method:

   • The maximum and minimum values of the stems are calculated by dividing the maximum and minimum values of the array by 10, respectively.
   • The array of integers is sorted in ascending order.
   • A loop iterates through the range of possible stems, from the minimum to the maximum, inclusive.
   • For each stem, the loop prints the stem followed by a pipe character and a space.
   • Another loop iterates through the array of integers and prints the leaf (the last digit of the integer) for each integer that falls within the current stem's range.
   • After printing the leaves for the current stem, the loop prints a newline character.

5. The program then waits for the user to press any key before exiting.

Overall, the code takes an array of integers, calculates the stems and leaves, and generates a stem-and-leaf plot, which is a useful visual representation of the data distribution.
