As we all know that poker cards have four suites: Spades, Hearts, Clubs and Diamonds with figures from 1 to 13.
Now you are given a set of poker cards, you can pick any one card as the first card. And except for the first card, you can only pick the card that has the same suit or figure with the previous one.
Return the max number of cards you can.
For example: [(H, 3), (H, 4), (S, 4), (D, 5), (D, 1)], it returns 3 as follows: (H,3)-->(H,4)-->(S,4)

Hey anyone got the 90 minutes online assessment test from Amazon for MBA interns? I would like to know what type of questions they ask in the assessment. I need an example if any one of you attended it.

Find the first non-repeated character in a string of characters. For example, 'c' for "abcbae".

Your input is a double array, and you can use *, +, -, and () parenthesis anywhere to create and output the maximum possible value.

Ex:
input is {3,4,5,1} --> output: 72
input is {1,1,1,5} --> output: 15

Follow up, if there are numbers <0


Already posted question ( 3yrs back)
my doubt is can we solve this using multiplication only ( special case 0 and 1 we need to use addition for these alone

ie. if ar[i]==1
max(result*ar[i-1]+1,result*ar[i+1]+1)
)

Adding an integer to a container or removing an integer from it. Providing an algorithm/method to find the largest integer in the container. (thinking of a larger set of data) (I believe that this question misses a conduction to have a reasonable solution)

Now given any number of balls, you have to tell how many times you have to weigh at minimum to find which ball is the heavier one?

What are the steps of the algorithm with order O(m log (mn)) for finding k-th smallest element (or median) of 2D array [1..M] [1..N] where each row of this matrix is sorted and independent from all other rows (ascending order, distinct elements)?

there are 3 tables :
Movie = {movie_id, .....}
Actor = {actor_id, gender, .....}
Movie_Actor = {movie_id, actor_id,....}
Find the pair of movie actor ( male) and actress ( female) who appeared in most movies together.

Tablea Order = {order_id, order_timestamp, total_sale_amount, ....}
Note => Trimmed Mean = remove top and bottom 5 percentile data to remove outliers. Take the average of middle 90% of the data.
you can use function percentile(Col_name, 0.95)
output should look like => {Date, raw_average, trimmed_average}

Power list has the following conditions
first element should b1
Next L2 element should be 2
Next L3 element should be 3
Next L4 element should be 4
Next L5 element should be 5
Next L6 element should be 6
Next L7 element should be 7
Next L6 element should be 6
...
Next L1 should be 1

e.g.,
1 2 3 4 5 6 6 7 6 5 4 3 2 1 -- power list
1 2 3 4 5 6 7 6 5 4 3 2 11 - not a power list since last two elements are 1 .

Wrte a code to find out whether arr [] represents a power list or not.

in Cracking the coding interview book 6th edition page 42 says that O(5 * 2^n + 1000 * N^100) = O(2^n)... I tried a sample code and got n^100 is greater than 2^n...
