[HITNO] Prebacivanje Pythona u PHP
Dakle imam slijedeći kod kojeg HITNO trebam prebaciti iz Pythona u PHP. Nadam se da onome ko poznaje Python (i PHP) ovo neće biti problem (nema baš nešto puno koda) :D. Unaprijed zahvaljujem :beer: Plaćam ako treba, ali valjda ima još dobrih kolega :)
Code:
def find_best_run (first_array, *argv):
# initialize data structures.
this_array_best_run = {}
for x in first_array:
this_array_best_run[x] = (1, (1,), (x,))
for this_array in argv:
# find the best runs ending at each value in this_array
last_array_best_run = this_array_best_run
this_array_best_run = {}
for x in this_array:
for (y, pattern) in last_array_best_run.iteritems():
(distinct_count, lengths, elements) = pattern
if x == y:
lengths = tuple(lengths[:-1] + (lengths[-1] + 1,))
else :
distinct_count += 1
lengths = tuple(lengths + (1,))
elements = tuple(elements + (x,))
if x not in this_array_best_run:
this_array_best_run[x] = (distinct_count, lengths, elements)
else:
(prev_count, prev_lengths, prev_elements) = this_array_best_run[x]
if distinct_count < prev_count or prev_lengths < lengths:
this_array_best_run[x] = (distinct_count, lengths, elements)
# find the best overall run
best_count = len(argv) + 10 # Needs to be bigger than any possible answer.
for (distinct_count, lengths, elements) in this_array_best_run.itervalues():
if distinct_count < best_count:
best_count = distinct_count
best_lengths = lengths
best_elements = elements
elif distinct_count == best_count and best_lengths < lengths:
best_count = distinct_count
best_lengths = lengths
best_elements = elements
# convert it into a more normal representation.
answer = []
for (length, element) in zip(best_lengths, elements):
answer.extend([element] * length)
return answer
# example
print find_best_run(
[1,4,8,10],
[1,2,3,4,11,15],
[2,4,20,21],
[2,30]) # prints [4, 4, 4, 30]
