Minimum Size Subarray Sum

Given an array of positive integers nums and a positive integer target , return the minimal length of a subarray whose sum is greater than or equal to target . Return 0 if there is no such subarray. This reads like an \(^{n}P_{k}\) permutation problem, where we&rsquo;re trying to minimize \(k\) under the constraint that the sum of elements is greater than target . \(^{n}P_{k}\) can be implemented…
