Every year, an investment firm invests into several companies' shares. Majority of their investments are in 3 companies: A, B and C. As they invest, they create a string of all of their investments in order. Given a string of their investments, determine the number of time periods they invested in the three major companies' shares. For example, given the investments as s = "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 s 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. Function Description Complete the function analyzelnvestments in the editor below. The function must return a long integer. analyzelnvestments has the following parameter(s): s: a string of length ni Constraints 1≤n≤105 • s[i] = {'A'...
