Solve Subarray Problems Quickly With Sliding Window Technique | FREE DSA Course in JAVA | Lecture 79
We have to solve a program known as the maximum sum subarray of size k.
So it means for a given size of subarray k, we have to find the maximum sum of all the subarrays of size k.
For example [2,9,31,-4,21,7] is an array, and k = 3.
Then for k=3 all subarrays are [2,9,31], [9,31,-4], [31,-4,21], [-4,21,7].
Hence the maximum sum is of [31,-4,21] which is 48. So the output will be 48.
Let's see how we can solve this question with a unique technique known as the sliding window technique which can help solve many questions of arrays in an efficient manner.
