&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;=== 처음 접근 ===&lt;br /&gt;
문제 자체 읽으면서 그냥 뻔해보이긴 했다. 이전에 디지털 공학 수업때 가산기에 대해서 배운바도 있었던 관계로. 그냥 머릿속에 대략의 할 일들이 그려졌다.&lt;br /&gt;
&lt;br /&gt;
그래서 첫 테스트를 바로 작성하였다.&lt;br /&gt;
&lt;br /&gt;
 class PrimaryArithmeticTest(unittest.TestCase):&lt;br /&gt;
     def testCarry(self):&lt;br /&gt;
         self.assertEquals(0,carryCount(123,456))&lt;br /&gt;
&lt;br /&gt;
하지만, 그렇다고 바로 알고리즘을 구현할 수 있는건 아니여서, 일단 다음과 같이만 작성하였다.&lt;br /&gt;
 def carryCount(one,two):&lt;br /&gt;
     result = 0&lt;br /&gt;
     return result&lt;br /&gt;
 &lt;br /&gt;
 class PrimaryArithmeticTest(unittest.TestCase):&lt;br /&gt;
     def testCarry(self):&lt;br /&gt;
         self.assertEquals(0,carryCount(123,456))&lt;br /&gt;
&lt;br /&gt;
그리고 할 일을 좀 생각해보았다.&lt;br /&gt;
&lt;br /&gt;
=== 1차 알고리즘 생각 ===&lt;br /&gt;
문제를 이리저리 나눠보니, 자리수 하나에 대해서 carry 가 발생하는지를 세는 것이 쉬워보였다. 그리고 해당 스트링을 일종의 list 로 나누는 것도 있으면 좋을 것 같았다. 그리고 carry 에 대해서 추후 앞자리에 더해주는 작업 등을 해야 할 것 같았다. 일단은 이정도 떠올리기로 하고, 앞의 두 일만 하였다.&lt;br /&gt;
&lt;br /&gt;
 def hasCarry(one,two):&lt;br /&gt;
     return one+two &amp;amp;gt;= 10&lt;br /&gt;
 &lt;br /&gt;
 .&lt;br /&gt;
 .&lt;br /&gt;
 &lt;br /&gt;
     def testCarryOne(self):&lt;br /&gt;
         self.assert_(not hasCarry(3,5))&lt;br /&gt;
         self.assert_(hasCarry(5,5))&lt;br /&gt;
         self.assert_(hasCarry(8,5))&lt;br /&gt;
 def toList(number):&lt;br /&gt;
 .&lt;br /&gt;
 .&lt;br /&gt;
 .&lt;br /&gt;
 &lt;br /&gt;
     def testToList(self):&lt;br /&gt;
         self.assertEquals([1,2,3], toList(123))&lt;br /&gt;
음.. 이 부분을 작성하던 중, 생각해보니 입력 데이터가 스트링이면 더 간단할 것 같았다. integer 단위로 더하기 보다는 자리수 단위로 생각할 것이란 생각이 들었다. 그래서 테스트 코드를 다시 바꾸었다. 그러고 보니, 그냥 구현할 방법이 떠오른다.&lt;br /&gt;
 def toList(numberStr):&lt;br /&gt;
     return [int(each) for each in numberStr]&lt;br /&gt;
 .&lt;br /&gt;
 .&lt;br /&gt;
 .&lt;br /&gt;
 &lt;br /&gt;
     def testToList(self):&lt;br /&gt;
         self.assertEquals([1,2,3], toList(&amp;#039;123&amp;#039;))&lt;br /&gt;
&lt;br /&gt;
=== 2차 ===&lt;br /&gt;
이 상태에서 &amp;#039;음.. 이정도 구현이면 어디까지 기능이 커버될까?&amp;#039; 라는 의문이 생겼다. 일단 만든 코드들을 연결해보았다.&lt;br /&gt;
 def carryCount(one,two):&lt;br /&gt;
     resultCount = 0&lt;br /&gt;
     oneList,twoList = toList(one),toList(two)&lt;br /&gt;
     for eachOne,eachTwo in zip(oneList,twoList):&lt;br /&gt;
         if hasCarry(eachOne,eachTwo):&lt;br /&gt;
             resultCount += 1&lt;br /&gt;
     return resultCount&lt;br /&gt;
 &lt;br /&gt;
 class PrimaryArithmeticTest(unittest.TestCase):&lt;br /&gt;
     def testCarry(self):&lt;br /&gt;
         self.assertEquals(0,carryCount(&amp;#039;123&amp;#039;,&amp;#039;456&amp;#039;))&lt;br /&gt;
         self.assertEquals(3,carryCount(&amp;#039;123&amp;#039;,&amp;#039;456&amp;#039;))&lt;br /&gt;
         self.assertEquals(1,carryCount(&amp;#039;123&amp;#039;,&amp;#039;456&amp;#039;))&lt;br /&gt;
일단 예제로 있던 테스트 3개에 대해서는 별 일 없이 돌아갔다. 이쯤에서 걍 끝낼까 하다가, 너무 허술해보이는 것들이 많아 보였다. 그래서 해당 상황과, 그 상황에 대한 테스트의 예를 추가해나갔다.&lt;br /&gt;
* 자릿수가 넘어가는 경우 - 1234 + 123&lt;br /&gt;
* 103 + 597 (즉, 0+9 가 1+9 가 되면서 carry 를 다시 발생시킬 때)&lt;br /&gt;
&lt;br /&gt;
carry 에 대해서는 별 생각을 안했다. 현재의 구조로는 carry 처리가 그리 이쁘게 나올 것 같지가 않았다. 코드를 좀 더 작성할까 하다가 일단은 green bar 에서 내부 자료 구조만 바꾸기로 했다.&lt;br /&gt;
일단, testToList 부터. 문제 스펙에서 &amp;#039;10자리 미만 수&amp;#039;라는 점을 그냥 이용해도 될 것 같다는 생각이 들었다.&lt;br /&gt;
 def withNullList(numberStr):&lt;br /&gt;
     result = [0 for each in range(10-len(numberStr))]&lt;br /&gt;
     numbers = [int(each) for each in numberStr]&lt;br /&gt;
     return result + numbers&lt;br /&gt;
 &lt;br /&gt;
 &lt;br /&gt;
     def testToList(self):&lt;br /&gt;
         self.assertEquals([0,0,0,0,0,0,0,1,2,3], withNullList(&amp;#039;123&amp;#039;))&lt;br /&gt;
         self.assertEquals([0,0,0,0,0,0,0,5,5,5], withNullList(&amp;#039;555&amp;#039;))&lt;br /&gt;
&lt;br /&gt;
여전히 테스트는 통과. 대략 추후 구현은 뻔해졌다. 자릿수 단위 계산 코드로 수정하였다.&lt;br /&gt;
 def carryCount(one,two):&lt;br /&gt;
     resultCount = 0&lt;br /&gt;
     oneList,twoList = withNullList(one),withNullList(two)&lt;br /&gt;
     for idx in range(9,-1,-1):&lt;br /&gt;
         if hasCarry(oneList[idx],twoList[idx]):&lt;br /&gt;
             resultCount += 1&lt;br /&gt;
             oneList[idx-1] += 1&lt;br /&gt;
     return resultCount&lt;br /&gt;
&lt;br /&gt;
이쯤 되니, 테스트 코드들은 전부 통과. main 코드 작성하고 약간 리팩토링. &lt;br /&gt;
혹시나 해서 마지막 테스트 추가함.&lt;br /&gt;
     def testCarry(self):&lt;br /&gt;
         testSet = [&lt;br /&gt;
                 [&amp;#039;123&amp;#039;,&amp;#039;456&amp;#039;,0],&lt;br /&gt;
                 [&amp;#039;555&amp;#039;,&amp;#039;555&amp;#039;,3],&lt;br /&gt;
                 [&amp;#039;123&amp;#039;,&amp;#039;594&amp;#039;,1],&lt;br /&gt;
                 [&amp;#039;103&amp;#039;,&amp;#039;597&amp;#039;,2],&lt;br /&gt;
                 [&amp;#039;1234&amp;#039;,&amp;#039;123&amp;#039;,0],&lt;br /&gt;
                 [&amp;#039;1234&amp;#039;,&amp;#039;236&amp;#039;,1],&lt;br /&gt;
                 [&amp;#039;999999999&amp;#039;,&amp;#039;1&amp;#039;,9]&lt;br /&gt;
                 ]&lt;br /&gt;
         for eachTest in testSet:&lt;br /&gt;
             one,two,expected= eachTest&lt;br /&gt;
             self.assertEquals(expected,carryCount(one,two))&lt;br /&gt;
마지막 경우도 역시 통과. 아까보다는 좀 더 나아보여서 이즈음에서 그만 둠.&lt;br /&gt;
&lt;br /&gt;
대략 끝나고 나니, 다르게 해결할 방법도 떠오름. 다른 방식으로 해결해도 재밌을 것 같다.&lt;br /&gt;
