/* The stocks of a company are being surveyed to analyze the net profit of the company over a period of several months. For an analysis parameter k, a group of k consecutive months is said to be highly profitable if the values of the stock prices are strictly increasing for those months. Given the stock prices of the company for n months and the…

Created August 28, 2021 22:03
Given a string, find the maximum consecutive repeating character in itself.
// given a string, give me the count of each particular character in the string.
// Hard mode: Give me the letter which is repeated the most in a row, regardless of how often the character appears in the string.
// “aaabbc” would return “a”

// “aaabbbbaacc” would return “b”
// “abababababcccababababababab” would return “c”

minSum.js - ah, this is from HackerRank, now it all makes more sense.
// I liked reduce. It's weird, but it's quirky, but I don't find it easy to understand at quick glance for all devs
const minSum_short = (num, k) => {
return new Array(k)
.fill(undefined) // not crazy about this aspect
.reduce(
(prev) => {
// Sort the array high to low
const current = prev.sort((a, b) => b - a)
// Swap the maximum value with the updated one
current[0] = Math.ceil(current[0] / 2)
