Describe a data structures that supports the stack push and pop operations and a third operation findmin, which returns the smallest element in the data structure, all in o(1) worst-case time.

The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.

The orbital diagram of an orbit containing 16 electrons will be as follows:

    1s²2s²2p⁶3s²3p⁴

The maximum number of electrons in each sublevel of the orbitals are:                  2 electrons for s-sublevel with one orbital                  6 electrons for p-sublevel with three orbital                  10 electrons for d-sublevel with five orbital                  14 electrons for f-sublevel with seven orbital
