Codility: MaxNonoverlappingSegments Solution

Approach

Compare current's start (A) with previous' end (B)

Implementation

1function solution(A, B) {
2  const N = A.length
3  let res = N ? 1 : 0
4  let prevB = B[0]
5  for (let i = 1; i < N; i++) {
6    if (A[i] > prevB) {
7      res++
8      prevB = B[i]
9    }
10  }
11  return res
12}
