## [Solution] Problems in your to-do list CodeChef Solution | CodeChef Problem Solution 2022

CodeChef recently revamped its practice page to make it easier for users to identify the next problems they should solve by introducing some new features:

• Recent Contest Problems - contains only problems from the last 2 contests
• Separate Un-Attempted, Attempted, and All tabs
• Problem Difficulty Rating - the Recommended dropdown menu has various difficulty ranges so that you can attempt the problems most suited to your experience
• Popular Topics and Tags

Like most users, Chef didn’t know that he could add problems to a personal to-do list by clicking on the magic '+' symbol on the top-right of each problem page. But once he found out about it, he went crazy and added loads of problems to his to-do list without looking at their difficulty rating.

Chef is a beginner and should ideally try and solve only problems with difficulty rating strictly less

than $1000$. Given a list of difficulty ratings for problems in the Chef’s to-do list, please help him identify how many of those problems Chef should remove from his to-do list, so that he is only left with problems of difficulty rating less than $1000$.

### Input Format

• The first line of input will contain a single integer $T$, the number of test cases. Then the testcases follow.
• Each testcase consists of 2 lines of input.
• The first line of input of each test case contains a single integer, $N$, which is the total number of problems that the Chef has added to his to-do list.
• The second line of input of each test case contains $N$ space-separated integers ${D}_{1},{D}_{2},\dots ,{D}_{N}$, which are the difficulty ratings for each problem in the to-do list.

### Output Format

For each test case, output in a single line the number of problems that Chef will have to remove so that all remaining problems have a difficulty rating strictly less than $1000$.

### Constraints

• $1\le T\le 1000$
• $1\le N\le 1000$
• $1\le {D}_{i}\le 5000$
