Given an array A of integers, we must modify the array in the following way: we choose an i and replace A[i] with -A[i], and we repeat this process K times in total. (We may choose the same index i multiple times.) Return the largest possible sum of the array after modifying ...
Since version 2.4, Ruby has provided a concise and elegant solution for summing an array of numbers: theArray#summethod. This method simplifies the process of calculating the sum of elements in an array. The syntax for using theArray#summethod is quite straightforward: ...
