personal opinions on data analysisAfter doing the data Product manager, has done some simple homework to the data analysis work, now records as follows, hoped can help the data product aspect schoolmate, simultaneously also takes this platform to exchange the study, the improper place, also please treatise.

Recent tasks have been a bit busy, mainly in the data analysis needs of various departments, coupled with the app backend performance optimization squeeze together.
The previous data-related work was mostly passive, and each department gave the data analysis requirements, and then a person analyzed the data from ES or Hadoop, and finally drew it with tableau, then expor
This article provides three different ways to invoke Ggplot in Python (IPython notebook).
In the large data age, data visualization is a very hot topic. Every bi manufacturer invests a lot of energy in the field of data visualization. Tableau, with its powerful data visualization capabilities, has become a hot-market company in Silicon Valley. Tableau data visualization of the product, its theoretical basi

Tableau
Tableau is the most powerful visualization tool, which is beyond doubt.
Tableau provides a wide range of visual charts with unique features, allowing you to update dashboard and dynamic data.
Similar to tableau, which is a self-help analysis tool, it is easy to learn. If the En
Several integers are placed in the array from small to large, and the user enters a number into the array, and the number in the array is still sorted from small to large. Ask the big guy to see what's wrong with this program?#include #include void Inserer (int *s,int x,int *n) {int i,j=0;while (JFor (i= (*n) -1;i>=j;i--) s[i+1]=s[i];S[i]=x;*n= (*n) +1;}void output (int *s,int *n) {int i; for (i=0;iprintf ("\ n");}int main (void) {int s[10]={1,6,7,10,14,18,22,29,36,47},x;int n=10; printf ("Entre
Question: a step has a total of n levels. If you can skip 1 level at a time, you can also skip 2 levels to find out the total number of hops in total and analyze the time complexity of the algorithm. Note: This question has frequently appeared recently. Companies that focus on algorithms, such as MicroStrategy, have chosen this question as an interview question or a pen question.
