Check If Each Element ≥ Previous

Write a C# Sharp program to check if the value of each element is equal or greater than the value of the previous element in a given array of integers.

Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
   class Program // Defining a class named 'Program'
   {
      static void Main(string[] args) // The entry point of the program
      {               
         // Outputting the result of the 'test' method with various integer arrays
         Console.WriteLine(test(new[] { 5, 5, 1, 5, 5 })); 
         Console.WriteLine(test(new[] { 1, 2, 3, 4 })); 
         Console.WriteLine(test(new[] { 3, 3, 5, 5, 5, 5 })); 
         Console.WriteLine(test(new[] { 1, 5, 5, 7, 8, 10 })); 
      }               

      // Method to check if an array is sorted in non-decreasing order
      static bool test(int[] numbers)
      {
         for (int i = 0; i < numbers.Length - 1; i++) // Loop through the array
         {
            if (numbers[i + 1] < numbers[i]) // Checking if the next element is less than the current element
            {
               return false; // If so, the array is not sorted, return false
            }
         }

         return true; // If the loop completes without finding elements out of order, return true
      }
   } 
}

Sample Output:

False
True
True
True

Flowchart:

Go to:

PREV : Shift Even Numbers Before Odd Numbers.
NEXT : Check for Two 15's Next to Each Other.
