In a way that shows the ability to find quick and clever ways to overcome difficulties.
She solved the problem resourcefully, using only the materials she had on hand.
Resourcefully → It is formed from "resource" (from Old French *resourse*, meaning a source or means of support) and the suffix "-fully" (meaning in a manner full of). The word "resourcefully" means in a manner full of resources or means to solve problems.
Think of having plenty of 'means' ('resource') to tackle challenges, and the '-fully' shows how you do it — that's why resourcefully means solving problems with plenty of resources.
