[] What algorithm is an algorithm

definition

Example: Algorithm Selection Sort

The pseudocode then describes:

void SelectionSort(int List[],int N){
    for(int i=0;i<N;i++){
        MinPosition=Scanformin(List,i,N-1);
        Swap(List[i],List[Minpostion]);
    }
}

Abstract pseudocode description. List may be a linked list. Swap function can write, you can write macros.
