Day 58 Of 100DaysOfcode: More About Algorithm

Todays I completed 58th day of #100daysOfCode and #python learning. Like yesterday today also continued to learned more about SQL properties(CROSS JOIN, UNION, UNION ALL, INTERSECT, EXCEPT) from Datacamp

Tired to complete some assignment from Coursera. Learned more types of algorithms from algorithmic toolbox. I tried to solve car fueling problem which is given below.

Python code

def compute_min_refills(distance, tank, stops):

    numrefill, currentrefill= 0,0
    stops = [0] + stops + [distance] #include the start and end points in the stops list   
    if distance <= tank:
        return 0
    else:
        while currentrefill < len(stops)-1:
            lastrefill = currentrefill
            #print(currentrefill, lastrefill, len(stops))
            while currentrefill < len(stops)-1 and stops[currentrefill+1] - stops[lastrefill]<=tank:

                currentrefill += 1

            if currentrefill == lastrefill:
                return -1
            if currentrefill < len(stops)-1:
                numrefill +=1

        #print(numrefill)

        return numrefill
if __name__ == '__main__':
    d, m, _, *stops = map(int, sys.stdin.read().split())
    print(compute_min_refills(d, m, stops))
