Understand the rvm usage. rvm --default use 1.9.3 will set 1.9.3 as default. You can use other ruby version by 'use', but you can always go back to default by rvm default

Two Sum

  • Given an array of integers, find two numbers such that they add up to a specific target number.

  • The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Please note that your returned answers (both index1 and index2) are not zero-based.

  • You may assume that each input would have exactly one solution. > Input: numbers={2, 7, 11, 15}, target=9

# This is probably the most tricky one - #

# When you invoke methods without parens, ruby looks at where you put the commas to figure out #
# where the arguments end (where the parens would have been, had you typed them) #
