An investment firm invested into 3 different companies’ shares: A, B and C. As they invested, they created a string of all of their investments in order. Given a string of investments, determine the number of time periods they invested in all three companies’ shares. For example, given the investments ass = “ABBCZBAC”, for total number of investments n = 7. Starting from the left, the first substring that contains an investment in all companies is ‘ABBC. There are 13 substrings of a which meet the criterion: “ABBC”, “ABBCZ”, “ABBCZB”, “ABBCZBA”, “ABBCZBAC”, “BBCZBA”, “BBCZBAC”, “BCZBA”, “BCZBAC”, “CZBA”, “CZBAC”, “ZBAC”, “BAC”) Note: Two substrings are considered different if the starting, ending, or both positions differ.

**Technifi Expert’s Answer:**

public class Result {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String s;
long investCount;
s = sc.next();
investCount = analyzeInvestments(s);
System.out.println(investCount);
}
public static long analyzeInvestments(String s)
{
long count = 0;
for(int i=0; i<=s.length()-3; i++)
{
for(int j=i+3; j<=s.length(); j++)
{
if(s.substring(i, j).contains("A") && s.substring(i, j).contains("B") && s.substring(i, j).contains("C"))
count++;
}
}
return count;
}
}
