    Why python is not available for this problem

    cpp

    One should take the input in this way

    int n; cin >> n; vector intVector(n); for (int i = 0; i < n; i++) { cin >> intVector[i]; }

    int s;
cin >> s;
vector<string> strVector(s);
for (int i = 0; i < s; i++) {
    cin >> strVector[i];
}

    Typescript

    'use strict';

process.stdin.resume();
process.stdin.setEncoding('utf-8');
let inputString: string = '';
let inputLines: string[] = [];
let currentLine: number = 0;
process.stdin.on('data', function(inputStdin: string): void {
    inputString += inputStdin;
});

process.stdin.on('end', function(): void {
    inputLines = inputString.split('\n');
    inputString = '';
    main();
});

function readLine(): string {
    return inputLines[currentLine++];
}

function main() {
    // Enter your code here
    while (readLine()) {
        const previousValue = parseInt(inputLines[currentLine - 1])
        
        const arr = inputLines.slice(currentLine, currentLine + previousValue)
        
        printArray(arr)

        currentLine += previousValue
    }
}

function printArray<T>(arr: Array<T>) {
    arr.forEach(item => console.log(item))
}
