Syntax error Number of Programmer Worked on given Time in Python

Number of Programmer Worked on given Time in Python

Suppose we have list of intervals and another input time. In each interval the structure is [start, end], this is representing the times when a programmer worked. We have to find the number of programmers that were working at time.

So, if the input is like interval = [[2, 6],[4, 10],[5, 9],[11, 14]], time = 5, then the output will be 3 as at time 5, there are three programmers, working [2, 6], [4, 10], [5, 9]

To solve this, we will follow these steps −

  • count := 0
  • for each interval in intervals, do
    • if start of interval <= time and end of interval >= time, then
      • count := count + 1
  • return count

Let us see the following implementation to get better understanding −

Example

 Live Demo

class Solution:
   def solve(self, intervals, time):
      count = 0
      for interval in intervals:
         if interval[0] <= time and interval[1] >= time:
            count += 1
      return count
ob = Solution()
interval = [[2, 6],[4, 10],[5, 9],[11, 14]]
time = 5
print(ob.solve(interval, time))

Input

[[2, 6],[4, 10],[5, 9],[11, 14]], 5

Output

3
