Here's my JavaScript question:

What is the best way to write a comparator function in JavaScript that takes 2 strings s1 and s2 and returns true if s1 is alphabetically before s2, and false otherwise?

You cannot use the built in sort function, you must create your own sort function. Input strings s1 and s2 are not case sensitive and might not be equal length.

Here's two examples: compare('aaa', 'aab') returns true, and compare('aaa', 'aaab') returns true..

Task 2: Compare strings. Write a function compare_strings() that takes pointers to two strings as inputs and compares the character by character. If the two strings are exactly same it returns 0, otherwise it returns the difference between the first two dissimilar characters. You are not allowed to use built-in functions (other than strlen()) for this task. The function prototype is given below: int compare_strings(char * str1, char * str2); Task 3: Test if a string is subset of another...

Implement the parseScores function (1 point) Implement the parseScores function to take a space-separated string of scores as an argument and return an array of score strings. Each score is a number in the range [0, 100]. Ex: "45 78 98 83 86 99 90 59" → ["45","78","98","83","86","99","59"] Hint: JavaScript's string split() function can...

In this assignment you will write a program that compares the relative strengths of two earthquakes, given their magnitudes using the moment magnitude scale. Earthquakes The amount of energy released during an earthquake -- corresponding to the amount of shaking -- is measured using the "moment magnitude scale". We can compare the relative strength of two earthquakes given the magnitudes m1 and m2 using this formula: f=10^1.5(m1−m2) If m1>m2, the resulting value f tells us how many times stronger m1...
