    Since this is looking for a solution without using any strings, I think even list concatenation doesn't count as a valid one. I think they are expecting more or less something along the lines of:

    if __name__ == '__main__':
    n = int(input())
    a = 0;
    for i in range(1, n+1):
        if (i > 99):
            a = a*1000 + i
        elif (i > 9):
            a = a*100 + i
        else:
            a = a*10 + i
    
    print(a)
