Nice 👍

[@harshmittal6461]

Really helpful video broo

[@armaan1610]

Glad it helped

[@top_10_2.O]

many a times I am able to make a correct logic for the questions but fail in implementation , either it take a lot time to implement the logic or sometimes I can't implement it, Please suggest something to overcome, I will definitely work on that.

[@armaan1610]

Do leetcode easy, medium for which you can make logic easily.. Then try to implement ki yourself.. If you can't or get stuck start reading editorial but in any case don't copy paste code... Understand and Implement ki yourself

[@TheAI-Tutor]

brother since how long you're coding and giving contests?
How to improve logic building mere bhai?
Pls tips dedo

[@armaan1610]

I have been giving contests from last 3 years ig.
about improving logic i think practicing harder problems than your comfortable rating range, makes you kill lower rating problem easily and fastly.
so, just do problems
1. which are not unsolvable by you currently
2. and also not which you already can solve easily.

if no diff then why it is not accepted

[@armaan1610]

@@gauravpunia4527 your code is absolutely correct. but the thing is 'ans' variable is overflowing . make it long long . then it will 'accepted'

what is the problem in my code?????? ignore the commented part
import java.util.*;
class Codechef {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int t = sc.nextInt();
for (int i = 0; i < t; i++) {
int n = sc.nextInt(); // Number of batsmen
int m = sc.nextInt(); // Number of bowlers
if(n>=4 && m>=4 && (n+m)>=11)
{
//permit to select the team members
int batsman[]=new int[n];
for(int j=0;jbowlers
//3---->batsman
//3 bowlers or batsman
for(int pn=0;pn=0 && bow>=0)

if(batsman[bat]>=bowler[bow])

bro i tried. and modified the code a bit. now it gives AC for first two and then runtime code ( I really don't know why ) - codeshare.io/nAPYjE
