arr (...read more
Ans. 
Find the length of the longest contiguous subarray that sums to zero in an array of integers.
• Iterate through the array and keep track of the running sum and its corresponding index in a hashmap.

• If the running sum is seen again, calculate the length of the subarray by subtracting the current index from the index stored in the hashmap.

• Update the maximum length of the subarray as you iterate through the array.
