They both have their own HP. Each round they dice respectively and get the points P1 and P2 (1 <= P1,P2 <= 6). Small number who,whose HP to reduce 1,the same points will remain unchanged. If one of them becomes 0 HP,he loses. As a result of technical differences between the two,each person has different probability of throwing 1,2,3,4,5,6. So we couldn’t predict who the final winner. </div><div class="panel_bottom" style="height: auto; margin: 0px; font-family: 'Times New Roman';font-size:14px; text-align: -webkit-center; background: url(http://acm.hdu.edu.cn/images/panel-bottom.png) 0% 0% no-repeat;"></div><br style="font-family: 'Times New Roman';font-size:14px; text-align: -webkit-center;" /><div class="panel_title" align="left" style="height: 38px; padding: 0px 14px; color: rgb(124,237); font-size: 18px; font-family: Arial; font-weight: bold; background: url(http://acm.hdu.edu.cn/images/panel-title.png) 0% 100% no-repeat transparent;">Input</div><div class="panel_content" style="height: auto; margin: 0px; padding: 0px 20px; font-size: 14px; font-family: 'Times New Roman'; background: url(http://acm.hdu.edu.cn/images/panel-content.png) repeat-y;">There are multiple test cases.
