Asymptotic notatation time complexity analysis and derivation. Patterns series arrays sorting searching similar to daily lives difference is that human speak english but digital computers understand zeros and ones. It get things simple and unbiased as choice is binary.. 1 or 0..yes or no.. high or low..true or false. Human brain have billion billion neurons each connected with 2000 to 5000 dendrites making entire universe of circuitry with great potential.. with help of stupid fast machines incredible heights are achievable..like billions of transistors fabricated nano technology embedded within few square millimetres quadratic array manner.
