Question

hello guys i need to sort some elements of integer in an integer array and need to store the index of the sorted list

assume if the elements in array are

x[]= {10,20,40,70,80,50,30};

i need to get the index of the sorted order say in this case i need to get 4,3,5,2,6,0 (ascending) (array x starting from 0)

Answer 1

Possible solution

 //sort the array intio a new array
 y[] = x;
 Arrays.sort(y); //sort ascending

 //final array of indexes
 int index_array[] = new int[7];

 //iteretate on x arrat
 for(int i=0; i<7; i++)
    //search the position of a value of the original x array into the sorted y array, store the position in the index array
    index_array[i] = arrays.binarySearch(x,y[i]);
