StringKey is slower than IntKey because matching from the character string is required. If IntKey, read array length, for(array length) { binary decode }. If StringKey, read map length, for(map length) { decode key, lookup by key, binary decode } so requires additional two steps(decode...

By specifying the index into the array of the character, individual characters may be accessed. It is important to note that strings are immutable (in other words the value of a string cannot be modified unless an entirely new string literal is assigned to the object). This means that while...
String values are surrounded by double quotes ("). For example: string myString = "This is a string"; A string declaration in C# cannot be spread over multiple lines. If a string needs to be split over multiple lines by new lines the \n special character can be used. For example: st...
