Jump Game
Explore how greedy techniques solve the Jump Game problem by evaluating steps you can jump from each array index. Learn to determine if reaching the last index is possible by examining allowed moves and applying optimal strategies.
We'll cover the following...
Statement
You are given an integer array nums, where each element represents the maximum number of steps you can move forward from that position. You always start at index (the first element), and at each step, you may jump to any of the next positions within the range allowed by the current element’s value. Return TRUE if you can reach the last index, or FALSE otherwise.
Constraints:
-
nums.length -
nums[i]
Examples
Understand the problem
Let’s take a moment to make sure you've correctly understood the problem. The quiz below helps you check if you're solving the correct problem:
Jump Game I
Given that we reach the last index, what is the output if nums = [1, 2, 3, 4, 5]?
TRUE
FALSE
