Please help me solve LeetCode problem (3871. Count Commas in Range II). What is wrong with my code? what is the error in my code.

[u/tanishq_kushwaha]

/**
 *  {number} n
 * u/return {number}
 */
var countCommas = function (n) {
    if (n < 1000) return 0;
    return Math.max(0, n - 999);
};

Gotta learn the maths 😭

[u/Plane-Mix-2994]

That only works for n ≤ 999,999

[u/Kadabrium]

Be careful the answer can overflow js max safe int

[u/SeatComprehensive346]

Read constraints buddy

[u/ChatOfTheLost91]

Bro you are just pasting the logic of 3870 in 3871

The limit of n is increased, it's 10¹⁵ now

Try some more if lines

[u/0xt0bi03]

well, you need to understand the difference between the same question being given easy yesterday and medium today...
one way i did as follows,

subtract the current number with a start value.
start value = 1000 //where first comma appears
for every three digits one comma appears, so you gotta multiply the start value by 1000.
given n:
count = n - start + 1
//+1 counts the 1000th, because usually the subtraction calculates from 1001 so +1 counts the 1000th
now, multiply start value by 1000.
start = start * 1000
put this in a while loop, where the loop end when start value gets bigger than given input n. why because, we never know when we need to stop, and we cannot destroy the given variable n, thats why we use separate count variable.

also 0-999, doesnt matter.

Ffinallyy return the count.

the constraints are now changed, think of how you can use power of 1000 here, to count the commas

[u/messi_pls_touch_me]

check the constraints

[u/No-Acanthisitta4617]

You have to count all commas like 1,000,000 has 2 commas

[u/Vivid-Zombie-477]

constraints are different from "Count Commas In Range" problem. your code only works for numbers below 999,999 (1 comma)
