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
