EIUARRAY - Array algorithms |
Chương trình sau bao gồm một số giải thuật cơ bản về Array, em hãy hoàn thiện các giải thuật này và chương trình kiểm tra.
Input
Dòng đầu tiên gồm hai số nguyên tương ứng là chiều dài của dãy số và số câu lệnh. Dòng thứ hai là dãy số
5 5 5 2 7 3 5 findMin findMax average indexOf 3 lastIndexOf 5
Output
2 7 4.4 3 4
