I think you might have clicked on few codeforces resources very frequently, so that the system suspected it as a crawler activity.

The second submission is now showing the accepted state. But I wanted to know under which scenarios, is the state shown in the image, possible? or is it really a bug?

Auto comment: topic has been updated by RKCROCKS144 (previous revision, new revision, compare).

Here is the code I had written.

process.stdin.resume();

let inputstring = '';
let currentLine = 0;

process.stdin.on('data', (inputStdin) => {
    inputstring += inputStdin;
    process.stdout.write("input Called\n");
});

process.stdin.on('end', () => {
    inputstring = inputstring.split('\n');
    let t = Number(inputstring[0]);
    let i = 1;
    process.stdout.write("End Called\n");
    while (t--) {
        let x = Number(inputstring[i++]);
        solve(x);
    }
});

function solve(n) {
    for (let i = n; i > 0; --i) {
        console.log(i);
    }
}

Why we are taking MEX of SUFFIX not that of PREFIX ? Please explain. Thanks.
