Problem
Given an integer array, output all the unique pairs that sum up to a specific value k.
So the input:
pair_sum([1,3,2,2],4)
would return 2 pairs:
(1,3)
(2,2)
Solution
def get_unique_pair(list_of_elems,k):
if len(list_of_elems) < 2:
print "Please increase data"
else:
seen = set()
output = set()
for num in list_of_elems:
target = k - num
if target not in seen:
seen.add(num)
else:
output.add(((min(num,target)),max(num,target)))
print output
get_unique_pair([1,3,2,2],4)
