Given a string str representing an integer and an integer led which is the count of LEDs available. The task is to check if it is possible to display the number using the given LEDs.
Note that a digit will be displayed as it is displayed on a 7 segment LED. If its possible to display the number then print Yes, otherwise print No.
Here’s an example of seven segment display:
Input: str = “999”, led = 5
9 takes 6 LEDs to be displayed. So 999 will require 18 LEDs
Since only 5 LEDs are available, it is not possible to display 999
Input: str = “123456789”, led = 43
Input: str = “123456789”, led = 20
Approach: Pre-compute the number of segments used by digits from 0 to 9 and store it. Now for each element of the string count the number of segments used by it. Now, if count ≤ led then print YES else print NO.
The number of segment used by digit:
0 -> 6
1 -> 2
2 -> 5
3 -> 5
4 -> 4
5 -> 5
6 -> 6
7 -> 3
8 -> 7
9 -> 6
Below is the implementation of the above approach:
- Check if mirror image of a number is same if displayed in seven segment display
- Maximum segment value after putting k breakpoints in a number
- Maximize the given number by replacing a segment of digits with the alternate digits given
- Maximum number that can be display on Seven Segment Display using N segments
- Check whether all the rotations of a given number is greater than or equal to the given number or not
- Check if a number is divisible by all prime divisors of another number
