Greedy Algorithms - Jump Game II (Minimum Jumps)
What is the output of the greedy jump function when called with input [0]?
What is the output of the greedy jump function when called with input [0]?
medium🧾 Code Trace Q4 of Q15
Step-by-Step Solution
Solution:
Step 1: Analyze loop range
len(nums) = 1, so range(len(nums)-1) = range(0), loop does not run.Step 2: Return jumps value
jumps initialized to 0, no increments, returns 0 without error.Final Answer:
Option D -> Option DQuick Check:
Single element means no jumps needed [OK]
Quick Trick: Single element array -> zero jumps needed [OK]
Common Mistakes:
MISTAKES- Expecting at least one jump
- Confusing zero-length loop behavior
Trap Explanation:
PITFALL- Some candidates expect an error or at least one jump even if array length is 1.
Interviewer Note:
CONTEXT- Tests handling of edge cases and loop boundaries.
