Suppose the stream is S={"1, 3, 2, 1, 2, 3, 4, 3, 1, 2, 3, 1"}
Let hash function be ℎ(x)=6𝑥+1 mod 5
Show how the Flajolet–Martin algorithm will estimate the number of distinct elements in this stream.

Flajolet Martin Solved Example 1: https://youtu.be/_-zxFg7JNak
Flajolet Martin Solved Example 2: https://youtu.be/daWtzs71AAA

FM algorithm estimates the number of distinct elements using the following steps:
Hash each element
Convert hash value to binary
Count number of trailing zeros in binary representation and store in R
Take maximum R
Estimate distinct count as:
Estimated distinct elements=𝟐^(𝑹_𝐦𝐚𝐱 )
