Let's say you are given an integer array. Create a function to determine the largest sum of any array's adjacent subarrays. For instance, the contiguous subarray with the largest sum is [4, -1, 2, 1]
in the array [-2, 1, -3, 4, -1, 2, 1, -5, 4]
.
You can employ a variant of Kadane's algorithm to resolve this issue. The steps are as follows:
- Set
max_so_far
andmax_ending_here
, two variables, to the first array element. - From the second element all the way to the end, traverse the array.
- Update the
max_ending_here
variable for each element by either adding the current element to it or setting it to the current element if it is larger than the sum of the previous elements. - If the
max_ending_here
variable is larger than themax_so_far
variable, update it. - The
max_so_far
variable holds the largest sum of any contiguous subarray after traversing the entire array.
The steps are optional to perform if you may like. The best one which wins is the shortest in length!
