After I read the problem statement, I didn't find out what's going on :-D. I think the most important part of the problem for me was these two sentences : "The clock has a scale marked in 30 degree increments ... She measured the angles of hands from a certain mark". Before I pay attention to these two sentences, I was confused of test case 3, I was thinking why 19 19 is impossible? Then I found that measured degrees are from a certain mark, so both of them can not be 19 19, but of course both of them can be 0 0, 30 30, 60 60, 90 90 ...
At first I was trying to solve the problem in this way : Which mark has she chosen to measure the degrees? 0? 30? 60? 90? 120? 150? 180? 210? 240? 270? 300? 330? I thought that I could map one of the degrees to one of these 12 origins, then map the other one, and check whether the resulted degrees show a true time? then I figured out that it's a little hard to implement. I tried to reverse my approach. I iterated h = 0 to 12 and m = 0 to 60 and each time I made mDegree and hDegree, at this moment I have to verify whether mDegree and hDegree is an answer or not? So I shifted both of them 0 degrees, 30 degrees, 90 degrees, 120 degrees, ... 330 degrees and checked whether they matched input or not, if yes I had found the answer. But at this time I checked though my approach seems true but test case 2 gave me time 07:01 that's 210 degrees and 6 degrees that if I add 30 to both of them it becomes 240 and 36 that matches test case 2, I read the problem statement again and I found that her measurement device supports integer degrees not real numbers, because 07:01 is not 210 degrees and 6 degrees, it is 210.5 and 6. So I added another condition to my program that if minute was odd it is not my answer. And Finally Accepted :-).
