Question

A cyber security firm is building a team of hackers to take down a network of cybercriminals. The skill level of the th hacker of team A is team_a[i] and of team B is b[i] A team is considered strong if for each index /at hacker is selected either from team A or team B, and the skill levels of the selected team are non- decreasing. Given two arrays team_a and team_b of n integers each, choose two indices

Answer 1

To solve this problem, one can use a two-pointer approach. one has to maintain two pointers, i and j, that traverse the arrays team_a and team_b, respectively. Initially, both pointers are at index 0.

A valid subarray exists if the skill level of the current element in team_a is less than or equal to the minimum skill level required for the corresponding element in team_b.

So, the Python Code is:

def getMaxSubarrayLen(team_a, team_b):

min_skill_b = []

i = 0

j = 0

max_len = 0

while i < len(team_a) and j < len(team_b):

if team_a[i] <= min(min_skill_b) or not min_skill_b:

if min_skill_b:

min_skill_b.pop()

min_skill_b.append(team_a[i])

i += 1

else:

j += 1

max_len = (j - i + 1) if max_len < (j - i + 1) else max_len

return (max_len or 0)

2. Hacker's Team

A cybersecurity firm is building a team of hackers to take down a network of cybercriminals. The skill level of the th hacker of team A is team_a[] and of team B is team_b[i]. A team is considered strong if for each index i a hacker is selected either from team A or team B, and the skill levels of the selected team are non-decreasing.

Given two arrays team_a and team_b of n integers each, choose two indices i and j such that the subarrays [team_a[i], team_a[i+1]...team_a[j]] and [team_b[i], team_b[i+1]...team_b[j-1]] can form a strong team. Find the maximum possible value of j-i+1, i.e. the length of the chosen subarray.

Example:

Given n=3, team_a=[5,2,4,1] and team_b=[3,6,2,2]

Optimal way to choose the subarrays:

- team_a[1] = 2 and team_b[2] = 2 form a strong team.

- team_a[2] = 4 and team_b[3] = 2 form a strong team.

Hence, the maximum subarray length that can be chosen to form a strong team is 3.

Function Description:

Complete the function getMaxSubarrayLen in the editor below:

getMaxSubarrayLen has the following parameters:

- int team_a[n]: skill levels of team A

- int team_b[n]: skill levels of team B

Returns:

- int: the maximum subarray length that can be chosen to form a strong team

Constraints:

1 ≤ n ≤ 105

1 ≤ team_a[i], team_b[i] ≤ 109
