Can't get the sample example

i don,t get how the output ends up as 61.200000

@kdanbhat hi,you can use the probability multiplication property in this question,in given sample case the maximum probability path will be 1 -> 4 -> 3 -> 5 and ans is 61.200000 using calculation:
61.200000 = 85(1–>4)*90(4–>3)*80(3–>5).
Hope you get it,try writing your code :slight_smile:
