wa了n次,请帮忙看一下代码//1083,解题思想,考察每个s【i】,t【i】对删除与其可兼容的对(即可同时发生的对),并把该对加入到检验条件,以检查下对数 #include <iostream> using namespace std; int main() { int T,N,sum=0,i,m,j,s[200],t[200]; char flag[200]; char biao; int rank[200],temp; cin >> T; while(T--) { cin >> N; for (i = 0;i < N;i ++) { flag[i] = '1'; cin >> s[i] >> t[i]; if (s[i]>t[i])//使s【i】小于t【i】 { temp = s[i]; s[i] = t[i]; t[i] = temp; } } sum = 0; for(i = 0;i < N;i ++) { temp = -1; if (flag[i] == '1')//s[i],t【i】对开始发生 { sum = sum + 10; rank[++temp] = i ;//把i对加入为检验条件 flag[i] = '0'; for (j = i +1;j < N;j ++)//检验剩下的对 { biao = '0'; for (m = 0;m <= temp;m++) { if (flag[j]=='0'||(flag[j]=='1'&&(s[j]>t[rank[m]]||s[rank[m]]>t[j]))) { continue; } if (flag[j] == '1') { biao = '1'; break; } } if (biao == '0'&&flag[j]=='1') { flag[j] = '0'; rank[++temp] = j; } } } } cout << sum << endl; } return 0; } Followed by:
