    code : n=int(input()) m=int(input()) total=(n+1)*(m>>1)

    m&1==m%2

    if(m&1): total+=(m>>1)+1 print(total)

    40 diem

    n=int(input()) m=int(input()) l=[1, n, 2, (n - 1), 3, (n - 2)] t=0 if n%2==0 and 1<=m<=n<=10**9: for i in range(1, m+1): t+=l[i-1] print(t)

    Code ne

    N = int(input("Nhap so N:")) M = int(input("Nhap so M:")) if M%2==0: a = m/2 T = a(N+1) else: a = (M-1)/2 T = (a(N+1))+((M+1)/2) print(T)

    a=int(input()) b=int(input()) tong=0 for i in range(a+1,b): if (i%2==0) and (i%3!=0): tong=tong+i print(tong) Test cuối vì sao quá thời gian
