Wrong character for string format on Integers section

[userunknownn]

In the section:

Write the test first

on the first line : You will notice that we're using %d as our format strings rather than %q. That's because we want it to print an integer rather than a string.

- You will notice that we're using %d as our format strings rather than %q. That's because we want it to print an integer rather than a string.
+ You will notice that we're using %d as our format strings rather than %s. That's because we want it to print an integer rather than a string.

[userunknownn]

Sorry, it was mentioned on the t.Errorf section, that this wraps the value on double quotes
