Solution: Frog Jump
Explore how dynamic programming can be applied to solve the Frog Jump problem by tracking all reachable jump lengths at each stone. Understand using maps and DP arrays to check valid moves, enabling you to determine if the frog can reach the last stone efficiently.
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
If the frog’s last jump was of length
