Solution: Frog Jump
Understand how to apply dynamic programming to solve the Frog Jump problem. This lesson helps you learn to track all possible jump lengths from each stone, use fast stone position lookups, and determine whether the frog can reach the last stone. You'll practice implementing a DP approach with a time complexity of O(n^2), helping build strong problem-solving skills for similar optimization challenges.
We'll cover the following...
Statement
A frog is trying to cross a river by jumping on stones placed at various positions along the river. The river is divided into units, and some units contain stones while others do not. The frog can only land on a stone, but it must not jump into the water.
You are given an array, stones, that represents the positions of the stones in ascending order (in units). The frog starts on the first stone, and its first jump must be exactly
