# ---------- REVERSE Bubble Sort Algorithm
# Bubble sort in reverse (greatest --> least)
# Very simple implementation due to straightforward
# layout of algorithm

# ---------- Imported modules
import inputoutput as io
import csv
import sys


# ---------- Main
target = sys.argv[1]

# ingress of data
numdata = io.ingressCSV(target)

# bubble sort operation
for i in range(len(numdata)):
        for j in range(0,len(numdata)-i-1):
            if numdata[j] < numdata[j+1]: #FIXME: flipped comparative op
                numdata[j], numdata[j+1] = numdata[j+1], numdata[j]

# finishing up, appending "-bubblesorted" to CSV
target = target[:-4]+"-reverse-bubble"+target[-4:]
