Question

Why doesn't this code work? PSet 2 #3

ctr = 1
n = 1
while ctr < 6:
for a in range(0, n):
for b in range(0, n):
for c in range(0, n):
if (6 * a) + (9 * b) + (20 * c) == n:
print ctr, 'a, b, c =',a,b,c
ctr += 1
n += 1
else:
n += 1
if x == 6:
print n,'is the highest number of McNuggests'

Answer 1

Why does this version work but not my originally listed:
ctr = 1
n = 1
nugget_purchase = False
while ctr < 6:
for a in range(0, n):
for b in range(0, n):
for c in range(0, n):
if (6 * a) + (9 * b) + (20 * c) == n:
print a,b,c,'lead to nugget purchase',n
nugget_purchase = True
if nugget_purchase == True:
ctr += 1
nugget_purchase = False
elif nugget_purchase == False:
print n,'cannot be bought'
ctr = 1
n += 1
print n

Answer 2

Your first code it incremented your ctr and your n under your for loop which means that for every number in the for loop it would add 1 to ctr and n if an answer was found.
