Zho:字串中插入指定字符

Working with 字串 can be difficult with limited options, but there are almost always workarounds. In a string, a character can be added. This tutorial explains the concept of inserting a character in a string. The scripts below are 函式积木 that are easier to work with. There are two basic methods for performing this: the 变量 Method and 清单 Method.

Variables Method
In this method, assume the following:
 * (changer) is the variable used to work with the transition of the character to the desired one
 * (item#) is the variable used to iterate through the string
 * (string) is the string input in the custom block that represents the character being inserted

定義 delete portion of (base) from (start) to (ending) 變數 [i v] 設為 [1] 變數 [result v] 設為 [] // starts blank 重複 ((start) - (1)) 次 變數 [result v] 設為 (字串組合 (result) 和 (字串中第 (i) 字\( (base) \))) 變數 [i v] 改變 (1) end 變數 [i v] 設為 ((ending) + (1)) 重複 ((字串長度\( (base) \)) - (ending)) 次 變數 [result v] 設為 (字串組合 (result) 和 (字串中第 (i) 字\( (base) \))) 變數 [i v] 改變 (1) end

List Method
For this method, assume the following:
 * (item#) is the variable used to iterate through the string
 * (letters) is the list which separates each letter of the string and modify it
 * (string) is the result of adding the new character to the string

定義 add (new character) at (letter #) of (string) //"string" is a string input that represents the character being inserted 變數 [item# v] 設為 (1) // the transferring of the variable's letters to the list starts with the first character 刪除第 [全部 v] 項 \( [letters v] \) // clears the list of letters 重複 (字串長度\( (string) \)) 次 新增項目 (字串中第 (item#) 字\( (string) \)) \( [letters v] \) // adds the current letter as a new item to the list 變數 [item# v] 改變 (1) // moves on to the next letter end // repeats the amount of characters there are in the variable represented by the input (string) 添加 (new character) 為第 (letter #) 項\( [letters v] \) // inserts the new character 變數 [string v] 設為 (letters :: list) // the variable is then set to the list of letters. (letters) is a combination of each letter of the list in own string

add [] at of []::custom // this is what the custom block looks like
