Lua编程

1. 将字符串分割成一个一个单元，存在表中

• 代码如下：

    local s = "sofgs啊等级高5584撒旦法规"
    local tb = {}
    for utfChar in string.gmatch(s, "[%z1-127194-244][128-191]*") do  
        table.insert(tb, utfChar)  
    end
  – 如果要提取出字符串中的数字
  
  local s1 = ""
  
  local s2 = ""
  
  for k,v in pairs(tb) do
  
  local n = tonumber(v)
  
  if n then
  
  s1 = s1…v
  
  else
  
  s2 = s2…v
  
  end
  
  end

2. 删除table中重复的值

• 代码如下：

    function unique(t, bArray)  
        local check = {}  
        local n = {}  
        local idx = 1  
        for k, v in pairs(t) do  
            if not check[v] then  
                if bArray then  
                    n[idx] = v  
                    idx = idx + 1  
                else  
                    n[k] = v  
                end  
                check[v] = true  
            end  
        end  
        return n  
    end

3. 判断一个table是否是另一个table的子集或相同

• 代码如下：

    local A = {33,24,11}
    local B = {24,50,33,12,11}
    local C ={}
    local isExistTable = {}
    for i=1,#A do
        table.insert(isExistTable,false)
    end
    for k1,v1 in pairs(A) do
        for k2,v2 in pairs(B) do
            if v1 == v2 then
                isExistTable[k1] = true                       
            end
        end
    end
    local isAdd = true
    for i,v in ipairs(isExistTable) do
        if v == false then
            isAdd = false
        end
    end
    if isAdd then
        table.insert(C,B)
    end
