Bit shift operations are not portable across all processor architectures, different processors can have different bit-widths. In other words, if you wrote int a = ~0; int b = a << 1; This value would be different on a 64 bit machine vs. on a 32 bit machine, or from an x86 based processo...

Kruskal's Algorithm is a greedy algorithm used to find Minimum Spanning Tree (MST) of a graph. A minimum spanning tree is a tree which connects all the vertices of the graph and has the minimum total edge weight. Kruskal's algorithm does so by repeatedly picking out edges with minimum weight (whi...

The DOM, or Document Object Model, is the API used by web browsers and other applications to access the contents of an HTML document.

They can appear both at the topmost level of a declaration (directly affecting the identifier) or at sub-levels (relevant to pointers only, affecting the pointed-to valu...
