insertion sort geeksforgeeks code example

Example 1: selection sort in java

public static void SelectionSort(int[] arr)
{
  int small;
  for (int i = 0; i <arr.length - 1; i++)
  {
    small = i;
    for (int j = i + 1; j < arr.length; j++)
    {
      //if current position is less than previous smallest
      if (arr[j] < arr[small])
      {
        small = j;
        
        //swap values
        int temp = arr[i];
        arr[i] = arr[small];
        arr[small] = temp; 
      }
  	}
  }
}

Example 2: insertion sort java

Insertion program
public class InsertionSortExample
{
   public void sort(int[] arrNum)
   {
      int number = arrNum.length;
      for(int a = 1; a < number; ++a)
      {
         int keyValue = arrNum[a];
         int b = a - 1;
         while(b >= 0 && arrNum[b] > keyValue)
         {
            arrNum[b + 1] = arrNum[b];
            b = b - 1;
         }
         arrNum[b + 1] = keyValue;
      }
   }
   static void displayArray(int[] arrNum)
   {
      int num = arrNum.length;
      for(int a = 0; a < num; ++a)
      {
         System.out.print(arrNum[a] + " ");
      }
      System.out.println();
   }
   public static void main(String[] args)
   {
      int[] arrInput = { 50, 80, 10, 30, 90, 60 };
      InsertionSortExample obj = new InsertionSortExample();
      obj.sort(arrInput);
      displayArray(arrInput);
   }
}

Example 3: insertion sort

// Por ter uma complexidade alta,
// não é recomendado para um conjunto de dados muito grande.
// Complexidade: O(n²) / O(n**2) / O(n^2)

function insertionSort(vetor) {
    let current;
    for (let i = 1; i < vetor.length; i += 1) {
        let j = i - 1;
        current = vetor[i];
        while (j >= 0 && current < vetor[j]) {
            vetor[j + 1] = vetor[j];
            j--;
        }
        vetor[j + 1] = current;
    }
    return vetor;
}

insertionSort([1, 2, 5, 8, 3, 4])

Example 4: selection sort

def ssort(lst):
    for i in range(len(lst)):
        for j in range(i+1,len(lst)):
            if lst[i]>lst[j]:lst[j],lst[i]=lst[i],lst[j]
    return lst
if __name__=='__main__':
    lst=[int(i) for i in input('Enter the Numbers: ').split()]
    print(ssort(lst))
