Perfect! Next up: we want to iterate over words
to add each word to our frequencies
hash, one at a time.
colors = { "red" => 2, "blue" => 3 } colors["blue"] += 1 puts colors["blue"]
- In the above example, we first create a hash mapping strings to integers.
- Then, we increment the value stored by
"blue"
by1
. - Finally, we print out
4
, the value stored by"blue"
.
Instructions
1.
Use .each
to iterate over the words
array.
For each word we find, assume that the word itself is a key in frequencies
and increment its value by 1.
This is why our default is 0
. The first time we find the word, it will have a default value of 0
that we can increment by 1
.
