Another alternative would be to create some kind of storage of counts of each character, e.g. LinkedHashMap(), but that would be … Read more

Simple answer to use recursion, If you don’t know recursion read that first void print_goals(int m,int n,int i,int j,string s) { if(i == m && j == n) { cout<<s+char(48+i)+’-‘+char(48+j)<<endl; return; } if(i<=m) print_goals(m,n,i+1,j,s+char(48+i)+’-‘+char(48+j)+’,’); if(j<=n) print_goals(m,n,i,j+1,s+char(48+i)+’-‘+char(48+j)+’,’); } call it as print_goals(5,2,0,0,””); where m=5 and n=2 0 solved permutation and combinations football score
