Codeforces 1407A Solution -- Ahahahahahahahaha Solution In Python

Program

t = int(input()) for i in range(t): n = int(input()) a = [int(i) for i in input().split()[:n]] k=0 if(n==1): if(a[0] == 1 and a[1] == 1): print(2) print('1 1') else: print(1) print(0) else: while (k < len(a) - 1): if(k%2==0): if(a[k]!=a[k+1]): if(a[k]==1): a[k] = 5 k+=1 else: a[k+1]=5 k+=1 else: k+=1 pass else: k+=1 pass x = [] j=0 while(j<n): if(a[j]!=5): x.append(a[j]) j+=1 print(len(x)) for l in range(len(x)): if(l==len(x)-1): print(x[l]) else: print(x[l], end=" ")

Output

Input ------- 4 2 1 0 2 0 0 4 0 1 1 1 4 1 1 0 0 -------- Output 1 0 2 0 0 3 0 1 1 4 1 1 0 0
