1、每20 批次处理数据，具体的还是要看细节部分def func(s1,s2):start=s1real_end=s2mark=int((s2-s1)/20)if mark==0:print("s1和s2分别是什么: %d - %d "%(start,real_end))else:fori in range(0,mark):end=start+20-1print

public class HelloWorld {public int unquePaths(int m,int n) {int [][]=new int[m][n]int i ,j;for(i=0;i<m;i++){for(j=0;j<n;j++){if(i==0||j==0){f[i][j]=1;}else{f[i][j]=f[i-1][j]+f[i][j-1];}.
