ERROR: type should be string, got "https://www.testdome.com/questions/python/two-sum/14289?questionIds=14288,14289&generatorId=92&type=fromtest&testDifficulty=Easy\n\nWrite a function that, given a list and a target sum, returns zero-based indices of any two distinct elements whose sum is equal to the target sum.
