// O(n) time

// O(1) space

func maxBalancedShipments(weight []int) int {

count := 0

for i := 0; i < len(weight) - 1; i++ {

if weight[i] > weight[i+1] {

count++

i++

}

}

return count

class Solution:

def maxBalancedShipments(self, weight: List[int]) -> int:

num_ = 0

running_max = 0

for i in range(len(weight)):

running_max = max(running_max, weight[i])

if weight[i] < running_max:

num_ += 1

running_max = 0

return num_

[Bhupathi Kakarlapudi]

class Solution:

def maxBalancedShipments(self, weight: List[int]) -> int:

ans = 0

mx = 0

for x in weight:

mx = max(mx, x)

if x < mx:

ans += 1

mx = 0 # Reset for the next segment

return ans
