如何在pine脚本中通过值float( value )和另一个字符串数组(Key)对数组进行排序？

//@version=4
study("Array Sort Example", overlay=true)

values = [3.14, 1.23, 2.56, 0.98, 4.67]
keys = ["Key1", "Key2", "Key3", "Key4", "Key5"]

//@sort_desc为升序排序，@sort_asc为降序排序
//@ascending = true表示升序，false表示降序
//@false为升序，true为降序
ascending = false

// 根据值进行排序
//@float(value)将value转换为浮点数
sort(indices, key) =>
    for i = 0 to (length(indices) - 1)
        for j = i + 1 to length(indices)
            if ascending ? key[i] > key[j] : key[i] < key[j]
                tmp = indices[i]
                indices[i] := indices[j]
                indices[j] := tmp

// 根据值进行排序
sortFloat(indices, key) =>
    for i = 0 to (length(indices) - 1)
        for j = i + 1 to length(indices)
            if ascending ? float(key[i]) > float(key[j]) : float(key[i]) < float(key[j])
                tmp = indices[i]
                indices[i] := indices[j]
                indices[j] := tmp

// 对数组进行排序
if ascending
    sortFloat(sorted_indices, values)
else
    sort(sorted_indices, values)

// 打印排序后的结果
for i = 0 to length(sorted_indices) - 1
    label.new(bar_index[i], values[sorted_indices[i]], tostring(values[sorted_indices[i]]), yloc=yloc.abovebar)
