GoodArray hackerrank solution for a number N, a goodArray is the smallest possible array that consists of only powers of two

Paladinen [302]

Using the knowledge in computational language in python it is possible to write a code that smallest possible array that consists of only powers of two.

<h3>Writting the code in python:</h3>

"public class GoodArray {"

"public static List<Integer> getQueryResults(long N, List<List<Integer>> queries) {"

"List<Integer> res = new ArrayList<>();"

int[][] arr = new int[queries.size()][3];

"List<Integer> goodArray = new ArrayList<>();"

"for (int i = 1; i <= N; i++) {"

"int num = i;"

"while (num % 2 == 0) {"

"goodArray.add(num);"

"num = num / 2;"

}

int index = 0;

for (List<Integer> l : queries) {

arr[index][0] = l.get(0);

arr[index][1] = l.get(1);

arr[index][2] = l.get(2);

index++;

}

Collections.sort(goodArray);

"for (int i = 0; i < arr.length; i++) {"

"int[] query = arr[i];"

int l = query[0];

int r = query[1];

int m = query[2];

int prod = 1;

"for (int j = l - 1; j <= r - 1; j++) {"

"prod = (int) (prod * goodArray.get(j)) % m;"

}

res.add(prod);

}

return res;

}

}

Create a series called 'directors' that contains each director's name and his or her average rating. Print out the type of your

sasho [114]

Using the computational language in python it is possible to write a code that we will use graphics to organize the names of the directors and the films they made.

<h3>Writing code in python:</h3>

import pandas as pd

df = pd.read_csv('all_data/movie_metadata.csv')

print('Shape: ',df.shape)

df.head()

name = df[['director_name','imdb_score']]

directors = name.groupby(['director_name']).mean()

directors = directors.reset_index()

directors = directors.stack()

print(directors,'\n')

print(type(directors),'\n')

print(directors[directors=='Steven Spielberg'],'\n')

print(directors[102]['imdb_score'])

miyazaki = df[df['director_name'] == 'Hayao Miyazaki']['movie_title']

print(miyazaki)

pivot_agg = pd.pivot_table(df,values='imdb_score', index=['country'], columns=['director_name'],aggfunc=np.median)

pivot_agg

gladiator_duration = df[df['movie_title']=='Gladiator\xa0']['duration']

gladiator_duration

I have an android tablet, when I charged it, it was at 23%. I put away my charger and just started playing. My percent didn't go

Irina-Kira [14]

Try resetting the tablet and see what happens. If that doesn't work you can hard reset it (This will remove everything on your device and make it look brand new)
