AtCoder Beginner Contest (ABC) 050解いてみました

A.

#input
N = raw_input()
A = []
A = raw_input().split()
A1 = A[:]
#even or odd

#N = odd
if N % 2 == 1:
    for i in range(N):
        if A1[i] % 2 == 0:
            A1[i] = True
        else:
             A1[i] = False
    if all(A1) == True:
        mx = max(A)
        print ( mx / 2 ) ** 2
    else:
        print 0

#N = even
elif N % 2 == 0:
    for j in range(N):
        if A1[i] % 2 == 1:
            A1[i] = True
        else:
            A1[i] = False
    if all(A1) == True:
        mx = max(A)
        print ( (mx + 1) / 2 ) ** 2
    else:
        print 0

B.

#input
T = []
N = int(raw_input())
T = raw_input().split()
M = int(raw_input())
PX = []
X = 0
T1 = []

#input matrix
for i in range(M):
    PX.append(map(int,raw_input().split()))


for j in range(M):
    #new time
    T1 = T[:]
    PJ = PX[j][0]
    XJ = PX[j][1]
    a = int(PJ)
    b = int(XJ)
    T1[a-1] = b
    
    #plus each time
    X = 0
    for k in range(N):
            X += int(T1[k])
    print X

C.勉強中
D.まだ無理
