Count 'abc' Substrings

Count 'abc' Substrings

You are given a string s. Your task is to count and output the number of times the substring \(abc\) appears in s as a contiguous sequence. The substring occurrences must be counted in a non-overlapping manner.

For example, if s = "abcabcabc", then the output is 3 since the sequence "abc" appears three times.

Note: If the string is empty or shorter than 3 characters, then the output should be 0.

inputFormat

The input consists of a single string s given via stdin. The string can contain any characters. You should consider the entire input as the string.

outputFormat

Output a single integer representing the number of times the substring \(abc\) appears in the input string s.
