Coding problem1
I dont remember much, but it was pretty easy round.
1. Boyer Moore Algorithm For Pattern Searching
Moderate
30m average time
70% success
0/80
Asked in companies
You are given a string ‘text’ and a string ‘pattern’, your task is to find all occurrences of pattern in the string ‘text’ and return an array of indexes of all those occurrences. You may assume that the length of ‘text’ is always greater than the length of ‘pattern’.
For example :
Let text = “this is a good place to have a good start”, pattern = “good” so you have to return {10, 31} because at 10 and 31 index pattern is present in the text.
Note :
If there is no such index in the text then just return an array containing -1.

I have solved this question on leetcode 2-3 times already, so I exactly knew what to do.
