... A 1-1 correspondence between sets A and B is another name for a function f : A → B that is 1-1 and onto. If f is a 1-1 correspondence between A and B, then f associates every element of B with a unique element of A (at most one element of A because it is 1-1, and at least one element of A because it ...

... since each open interval (a, b) in S is contained in Sn,m when n > 1/(b − a) and m ≥ max(|a|, |b|). Thus, S is a countable union of finite sets and hence countable. 4. There is an uncountable set of nested subsets of N. Because Q is in one-to-one correspondence with N, it suffices to find subsets of ...

Exercises: Arrays
... Write a program to read an array of real numbers (space separated values), round them to the nearest integer in “away from 0” style and print the output as in the examples below. Rounding in “away from zero” style means: To round to the nearest integer, e.g. 2.9 3; -1.75 -2 In case the numbe ...
