C 言語では、文字列内の 2 つの同一の文字の間にある最大文字数

1. 2‘a’ first index 0 last 5 , characters in between 5-0-1=4
2. ‘b’ first index 1 last 4 , characters in between 4-1-1=2
   Maximum character in between repeating alphabets : 4

1. ‘A’ first index 0 last 3 , characters in between 3-0-1=2
2. ‘b’ first index 1 last 7 , characters in between 7-1-1=5
3. ‘c’ first index 2 last 6 , characters in between 6-2-1=3
   Maximum character in between repeating alphabets : 5
