Big O notation means the algorithm runs in the order of "c""n", and the big O notation ignores the constant "c". This can be written as "c""n" = O("n"). If, however, an algorithm runs in the order of 2, replacing "n" with "cn" gives 2 = (2). This is not equivalent to 2 in general. Changing variables may also affect the order of the resulting algorithm. For example, if an algorithm's run time is "O"("n") when measured in terms of the number "n" of "digits" of an input number "x", then its run time is "O"(log "x") when measured as a function of
