🧵 C# Tip: string.Split vs Regex.EnumerateSplits
✅ string.Split es rápido y sencillo para separadores fijos.
✅ Regex.EnumerateSplits es perfecto para patrones complejos y para procesar texto de forma incremental, generando cada fragmento solo cuando lo necesitas, lo que reduce el uso de memoria.
Sigue leyendo👇
Cuando necesitas dividir cadenas, en C# tienes dos opciones populares:
🔹 string.Split
👉 Fácil y rápido para separadores fijos (como una coma , o espacio).
👉 Devuelve un arreglo con todas las partes de una vez.
👉 Ideal para textos pequeños y casos simples.
🔹 Regex.EnumerateSplits
👉 Permite usar patrones complejos con múltiples caracteres o combinaciones ([ ,;], palabras, etc.).
👉 Retorna un IEnumerable<string> perezoso: genera cada fragmento bajo demanda, sin crear todo el arreglo de golpe.
👉 Perfecto para textos grandes o procesamiento incremental.
👉 Mejor uso de memoria y fácil integración con LINQ.

StringSplit関数の引数にstring配列の参照があるけど、
リファレンス含めて動的配列をArrayResizeしないで渡すサンプルコードばかり。
これでメモリ破壊しないならStringSplit関数内部でArrayResizeしてる？
動的配列の宣言がローカルならスコープから外れた際にArrayFreeしてるのかな🤔

Subtraction (cannot negate a variable to use Add)
Floating point math
StringSplit("123", "") should return ["1", "2", "3"] instead of "123"
array concat/append
object GetItem
IsArray/IsObject
A better description of how contains and unique works

(*3主張の検証*)s=Import["raw.githubusercontent.com/To…","Data"];
t=Map[ToExpression[StringSplit[#,"/"]]&,s];
Union@Flatten@t==Range@512
And@@Flatten@Map[CoprimeQ@@#&,t,{2}]
M=ToExpression@s;MatrixForm@M
A=ArcTan@M;Union@FullSimplify@Flatten@{Total@A,Total@Transpose@A,Tr@A,Tr@Reverse@A}
凄い魔方陣が出来てしまった。
使われている数字は1～512を重複なしで1回ずつ、全て既約真分数。
全てのマス目をatan(x)してから足すと、縦横斜めが全て2πになる。

Sure, sex is great.... But have you ever gone back to analyze old data with perfectly labeled variables to split into columns? #satisfaction #stringsplit #r #data #nerdlife 🤓
