题目一、给一个表，表里有5个数，在[0-13]之间，其中0可以表示任意数，判断这个表是否连续思路：连续的条件：1、表中都是02、表中有4个03、0个数不大于3，经过排序之后除去0之外，最大值减去最小值的差小于5注意：要排除掉除去0之外的数里面有相同的数local list = {
   0,0,2,5,1}function toCheck ()    table.sort(list) -- 把数组从小到大排序    local zero_num = 0    for k,v in pairs(list) do         if v == 0 then             zero_num = zero_num + 1         elseif v ~= 0 then             for i = k+1,#list do                    if v == list[i] then                      print("该表不连续")                       return                   end                end         end                  end    if zero_num == 4 or zero_num ==5 then      print("该表连续")     elseif list[#list] - list[zero_num + 1] < 5 then      print("该表连续")    else      print("该表不连续")    endendtoCheck()

 

题目二、如何将一组数据等概率打乱？t = {
   1,2,3,4,5,6,7,8,9}local function shuffle(t)    if not t then return end    local cnt = #t    for i=1,cnt do        local j = math.random(i,cnt)        t[i],t[j] = t[j],t[i]    endendshuffle(t)for k,v in pairs(t) do    print(v)end

 

题目三、将一个数组从小到大排序，然后将重复出现的数字全部删除(后续数字往前移)local t = {
   4,2,3,4,1,6,5,8,7}local newArray = {}table.sort(t)newArray[1] = t[1]for i = 2,#t do    if t[i] ~= t[i - 1] then        newArray[i] = t[i]    endendfor k,v in pairs(newArray) do    print(v)end

 

题目四、编写一个函数，将某个数组分成两个数组，一个存放偶数，一个存放奇数local t = {
   4,2,3,4,1,6,5,8,7}function device(array)    local oushuArr = {}    local jishuArr = {}    for i = 1,#array do        if t[i] % 2 == 0 then            oushuArr[#oushuArr + 1] = array[i]        else            jishuArr[#jishuArr + 1] = array[i]        end    end    return oushuArr,jishuArrendlocal a,b = device(t)for k,v in pairs(a) do    print(v)endprint("=========")for k,v in pairs(b) do    print(v)end
