Given an array of integers ARR
of size N, consisting of 0s and 1s, you need to select a sub-array and flip its bits. Your task is to return the maximum count of 1s that can b...
Given an array of 0s and 1s, find the maximum count of 1s by flipping a sub-array at most once.
Iterate through the array and keep track of the maximum count of 1s obtained by flipping a sub-array.
Consider flipping a sub-array from index i to j and calculate the count of 1s in the resulting array.
Return the maximum count of 1s obtained by flipping a sub-array at most once.

Data frames are a data structure used for storing and manipulating tabular data in R programming language. Assembly language is a low-level programming language that is used to write programs that can directly interact with the hardware of a computer. Dynamic programming is a technique used to solve complex problems by breaking them down into smaller subproblems and solving them recursively.
Data frames are commonly use...
