Insertion Sort Algorithm

By DaPrimitive Soource -

♣ PSEUDOCODE ::
INSERTION-SORT(A)
    for j = 1 to A.length - 1
        key = A[j]
        // Insert A[j] into the sorted sequence A[0 ... j-1].
        i  = j - 1
        while i >= 0 and A[i] > key
            A[i + 1] = A[i]
            i = i - 1
        A[i + 1] = key

♣ C / C++ Code ::
void InsertionSort(int A[], int len)
{
    int i, j, key;
    for(j = 1; j <= len-1; j++) {
        key = A[j];
        i = j - 1;
        while(i >= 0 && A[i] > key) {
            A[i+1] = A[i];
            i--;
        }
        A[i+1] = key;
    }
}

♣ JAVA Code ::
static void InsertionSort(int A[]) {
    int i, j, key;
    for (j = 1; j <= A.length - 1; j++) {
        key = A[j];
        i = j - 1;
        while (i >= 0 && A[i] > key) {
            A[i + 1] = A[i];
            i--;
        }
        A[i + 1] = key;
    }
}

♣ PHP Code ::
function InsertionSort($A, $len) {
    for($j=1; $j<=$len-1; $j++):
        $key = $A[$j];
        $i = $j - 1;
        while($i >= 0 && $A[$i] > $key):
            $A[$i+1] = $A[$i];
            $i--;
        endwhile;
        $A[$i+1] = $key;
    endfor;
    return $A;
}

সাহল ইবনে হুনাইফ (রাঃ) হতে বর্ণিত আছে, তিনি বলেন, রাসূলুল্লাহ (সাঃ) বলেছেনঃ যদি কোন লোক পবিত্র অন্তরে শাহাদাত লাভের উদ্দেশ্যে দু'আ করে তাহলে সে নিজের বিছানায় মারা গেলেও তাকে আল্লাহ শহীদদের স্তরে পৌঁছিয়ে দেবেন । (মুসলিমঃ ১৯০৯)

C++ :: Topological Sort Algorithm (using DFS)

By DaPrimitive Soource -
Image
A topological sort of a dag G = (V,E) is a linear ordering of all its vertices such that if G contains an edge (u,v), then u appears before v in the ordering. (If the graph contains a cycle, then no linear ordering is possible.) PSEUDOCODE TOPOLOGICAL-SORT(G) call DFS(G) to compute finishing times v.f for each vertex v as each vertex is finished, insert it onto the front of a linked list return the linked list of vertices

C++ :: Strongly Connected Components Algorithm (SCC)

By DaPrimitive Soource -

Many algorithms that work with directed graphs begin with such a decomposition. After decomposing the graph into strongly connected components, such algorithms run separately on each one and then combine the solutions according to the structure of connections among components. ALGORITHM STRONGLY-CONNECTED-COMPONENTS(G) call DFS(G) to compute finishing times u.f for each vertex u compute GT call DFS(GT), but in the main loop of DFS, consider the verteces in order of decreasing u.f (as computed in line 2) output the vertices of each tree in the depth-first forest formed in line 4 as a separate strongly connected component
