randsubseq!

randsubseq!(S, A, p)

Like randsubseq, but the results are stored in S (which is resized as needed).

Examples

1. Generate a random subsequence of an array:

   julia> arr = [1, 2, 3, 4, 5];
   julia> subseq = Int[];
   julia> randsubseq!(subseq, arr, 0.5)
   2-element Array{Int64,1}:
   1
   4

   This example generates a random subsequence of the array arr with a probability of 0.5 for each element. The resulting subsequence is stored in the subseq array.

2. Generate a random subsequence of a string:

   julia> str = "Julia Programming";
   julia> subseq = String[];
   julia> randsubseq!(subseq, str, 0.3)
   6-element Array{String,1}:
   "i"
   "a"
   "P"
   "g"
   "m"
   "g"

   It generates a random subsequence of the string str with a probability of 0.3 for each character. The resulting subsequence is stored in the subseq array of strings.

3. Generate a random subsequence of a range:

   julia> rng = 1:10;
   julia> subseq = Int[];
   julia> randsubseq!(subseq, rng, 0.7)
   7-element Array{Int64,1}:
   1
   2
   4
   6
   7
   8
   9

   It generates a random subsequence of the range rng with a probability of 0.7 for each element. The resulting subsequence is stored in the subseq array.

Common mistake example:

julia> arr = [1, 2, 3, 4, 5];
julia> subseq = Int[];
julia> randsubseq!(subseq, arr, 1.5)
ERROR: ArgumentError: probability must be in the range [0, 1]

In this example, the probability provided is outside the valid range of [0, 1]. The probability argument must be a valid probability value between 0 and 1. Be sure to provide a valid probability value when using randsubseq!.
