Coding problem1
1. Count Number of Subsequences
Moderate
15m average time
85% success
0/80
Asked in companies
Given an array of non-negative integers ‘A’ and an integer ‘P’, find the total number of subsequences of ‘A’ such that the product of any subsequence should not be more than ‘P’.
A subsequence is a sequence that can be derived from another sequence by deleting some or no elements without changing the order of the remaining elements.
Note
You need to print your answer modulo 10^9 + 7.
For Example
Let us take A = [1,2,3] and P = 4.
All the subsequences not having product more than ‘4’ are {1}, {2}, {3}, {1,2}, {1,3}. Therefore count is equal to ‘5’.
Problem approach
Step 1 : I first applied bubble sort. It was not good enough.
Step 2 : Interviewer asked me to optimise the solution.
Step 3 : Then i gave solution with merge sort and interviewer was happy.
