Instructions

Have a look at the following numbers.

n	score
1	50
2	150
3	300
4	500
5	750

Can you find a pattern in it? If so, then write a function getScore(n)/get_score(n)/GetScore(n) which returns the score for any positive number n.

Note Real test cases consists of 100 random cases where 1 <= n <= 10000

My solution:

function getScore(n) { let r = 0; for(let i = 1; i<=n; i++){ r += i*50 } return r } Enter fullscreen mode Exit fullscreen mode

Explanation

First I had to identify the pattern, I saw that every score is equal to the sum of each number by 50, I did a for loop that iterated until "i" is equal to "n", and in each iteration I summed the "r" actual value plus the result of "i" by 50, that way I can get the last result.

let r = 0; for(let i = 1; i<=n; i++){ r += i*50 }

at the end of the for loop I just returned "r"

return r
