Battery capacity dropped from 97% to 30%. Is it ubuntu's problem?

Question

The input will be

8 // the numbers of block

1 4 // block A: from 1 to 3

8 11

5 7

3 6

9 13

2 6

5 9

8 14 // block H from 8 to 13

The question is to compute the minimum steps to move from the 1st block to the last block, which means, from A to H. You can move right or left on the same block, and you can jump straight to another block if they overlap on the number line, for example, you can jump from A to D or F, you can jump from C to D, or F, or G.

Here, the answer is 3. A -> D -> G -> H (or A -> F -> G -> F)

How can I solve this problem? Please, thanks!

Solution

There was no problem with Ubuntu, Because it displays only the information what it gets from the battery.

It means that your battery was dying out soon.(99%)

Battery sensors may-be sending wrong Information.

I think you were right about the battery sensors sending wrong information. I removed the battery , then placed it back and now it is showing the correct reading and working fine.
