大家来看我的题解 (可能有点复杂,还用了常量，小题大做) 我正数的累加器用了ac作变量名;负数我用了wa做变量名(懂的都懂) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

#include<iostream> using namespace std; int main(){ int n,a,sum2=0,sum1=0; cin>>n; for(int i=0;i<n;i++){ cin>>a; if(a>0){ sum2++; } if(a<0){ sum1++; } } cout<<sum2<<" "<<sum1; }

cishu = int(input()) lis = [] zhengshu = [] fushu = [] for i in range(cishu): a = int(input()) lis.append(a) for j in lis: if j == 0: pass elif j > 0: zhengshu.append(j) else: fushu.append(j) print(len(zhengshu),len(fushu))
