• Example: function outerFunction() { let outerVar = 'I am oute...read more

Kadane's Algorithm is used to find the maximum subarray sum in an array.

• Iterate through the array and keep track of the maximum sum ending at each index.

• If the sum at any index becomes negative, reset the sum to 0.

• Return the maximum sum found.

• Example: For array [-2, 1, -3, 4, -1, 2, 1, -5, 4], the maximum subarray sum is 6 (from index 3 to 6).
