Problem 5

[nman52]

I've figured out the out of index issue, doesn't look pretty but..

def compress(z):
    
    count = 1
    list = []
    
    i = 0
    
    
    print(len(z))
    
    for value in z:
        while i+1 < len(z):
            if z[i] == z[i+1]:
                count = count+1
                print(count)
                i += 1
        else:
            print("")
