Min Subarray Length

Prompt

Write a function called minSubArrayLen which accepts two parameters - an array of positive integers and a positive integer. This function should return the minimal length of a contiguous subarray of which the sum is greater than or equal to the integer passed to the function. If there isn't one, return 0 instead.

const router = require('express').Router()
const {User, Subscription} = require('../db/models')
const webPush = require('web-push')
module.exports = router


router.post('/', async (req, res, next) => {
  try {
    // Our app has 4 defferent option for reminder, so depends on 
    // which reminder gets called, payload is changed.
