Largest Consecutive Subarray

MediumPython

Problem

Given an array, find the largest subarray that contains consecutive elements (by value).

Treat the values as reorderable, so a valid subarray may not be sorted, but it must contain distinct integers with no gaps. Return the inclusive [start, end] indices of the longest valid subarray; if multiple subarrays tie, return the one with the smallest starting index. Assume the array is non-empty.

Constraints

  • 1 <= nums.length <= 10^4
  • -10^9 <= nums[i] <= 10^9
  • Return inclusive zero-based indices
  • A valid subarray must contain distinct values
