if __name__ == "__main__":
    N = 10
    # input data
    print 'please input ten num:\n'
    l = []
    for i in range(N):
        l.append(int(raw_input('input a number:\n')))
    print
    for i in range(N):
        print l[i]
    print

    # sort ten num
    for i in range(N - 1):
        min = i
        for j in range(i + 1,N):
            if l[min] > l[j]:min = j
        l[i],l[min] = l[min],l[i]
    print 'after sorted'
    for i in range(N):
        print l[i]
