"stdout error"  on executing below code in interpreter.

def stdin(s):
    if (len(s)>=2 and len(s)<=10000):
        ev=[s[i] for i in range(len(s)) if i%2==0]
        od=[s[i] for i in range(len(s)) if i%2!=0]
        even=''.join(map(str,ev))
        odd=''.join(map(str,od))
        print("{0} {1}".format(even,odd))
if __name__ == '__main__':
    s = input().strip()
    stdin(s)
