text: Difference between Insertion sort and Selection sort | Java program for the above approach ; Function to sort an array using insertion sort ; Move elements of arr [ 0. . i - 1 ] , that are greater than key to one position ahead of their current position ; Function to print an array of size N ; Print the array ; Driver code ; Function Call
code: import java . util . * ; class GFG { static void insertionSort ( int arr [ ] , int n ) { int i , key , j ; for ( i = 1 ; i < n ; i ++ ) { key = arr [ i ] ; j = i - 1 ; while ( j >= 0 && arr [ j ] > key ) { arr [ j + 1 ] = arr [ j ] ; j = j - 1 ; } arr [ j + 1 ] = key ; } } static void printArray ( int arr [ ] , int n ) { int i ; for ( i = 0 ; i < n ; i ++ ) { System . out . print ( arr [ i ] + " ▁ " ) ; } System . out . println ( ) ; } public static void main ( String [ ] args ) { int arr [ ] = { 12 , 11 , 13 , 5 , 6 } ; int N = arr . length ; insertionSort ( arr , N ) ; printArray ( arr , N ) ; } }
