I had an online interview on September 13, 2024.

The interview process involved solving two questions within 90 minutes.

After that, I had two more segments where I had to make workday-related decisions.

For example, I was asked to determine which databases I would use to build a voting system with product requirements for a 5-minute duration and display live voting counts.

Create a function that takes a slice of 32-bit integers and a number of channels, k, as input. The goal of this function is to split all the integers from the array between the channels (arrays) in such a way that it maximizes the sum of the medians of all the channels. It's important to note that each channel must hold at least one integer.

You are given a string s of length n. Your task is to return the next nice string based on lexicographical order of length n. A nice string is defined as a string in which no two adjacent characters are the same. For example, "abb" is not a nice string because "bb" are duplicate adjacent characters.

Please note that if the string contains "zz", it cannot be transformed into a nice string, and in such cases, you should return "-1". Additionally, the character 'z' cannot be increased, as it is the last character and cannot be transformed into 'a'.
