用LUA实现几天简单的题目

这三个函数用穗孝 Lua 实现分别如下：

function PrintLower(str)

print(str:lower())

end

function MergeAndSort(array1, array2)

local array = {}

for _, elem in ipairs(array1) do

table.insert(array, elem)

end

　猜咐稿　

for _, elem in ipairs(array2) do

table.insert(array, elem)

end

table.sort(array)

for _, elem in ipairs(array) do

　简亩　io.write(elem, ', ')

end

end

function PrintDigitsAndReverse(num)

local digits = math.ceil(math.log(num)/math.log(10))

print("The digit of " .. num .. " is " .. digits)

print("The reversed number is ")

while num >0 do

local lastDigit = num % 10

io.write(lastDigit)

num = (num - lastDigit) / 10

end

end

function bind(f,v)

 如型笑 return 渣含租羡function(...)

    return f(...,v)

  end

end
