G l (x) is pseudorandom, when x is uniformly random. One additional pseudorandom bit implies polynomially more pseudorandom bits. It can be shown that if there is a pseudorandom generator G l: {0,1} l → {0,1} l+1, i.e. a generator that adds only one pseudorandom bit, then for any m = poly(l), there is a pseudorandom generator G' l: {0,1} l ...
There have been a fairly small number of different types of (pseudo-)random number generators used in practice. They can be found in the list of random number generators, and have included: Linear congruential generator and Linear-feedback shift register; Generalized Fibonacci generator; Cryptographic generators; Quadratic congruential generator
Hotlines are alternative numbers used in place of telephone numbers as a means of dialing a service. Hotlines are usually five digits long and are displayed in advertising and menus. Hotlines starts with numbers described below. An example of a hotline is 16789 reserved for Egypt Post. Other examples of hotlines include: [4] Information Crimes ...
Land line phone numbers in Vietnam follow the format Area Code + Phone Number. The area codes depend on the province and/or city. To dial a number within the same province or city, only the phone number needs to be dialed. When dialing from a different province/city or from a mobile phone, follow the format 0 + Area Code + Phone Number.
National (significant) number: 10 Digits. Area code: 3 digits; Local subscriber's number: 7 digits. Only exception in this is the call center numbers which start with 444, the call center numbers cannot be dialed with area code, they must be dialed with 7 digit from any phone (Landlines & Mobiles) in the country. The number format is 444 XX XX.

Before modern computing, researchers requiring random numbers would either generate them through various means (dice, cards, roulette wheels, [5] etc.) or use existing random number tables. The first attempt to provide researchers with a ready supply of random digits was in 1927, when the Cambridge University Press published a table of 41,600 ...
