Vending Machine Dispense

This problem simulates a vending machine that accepts money in cents and dispenses an item if sufficient funds are provided. The machine offers three items:

• chips costing \(50\) cents
• soda costing \(75\) cents
• candy costing \(100\) cents

If the inserted amount is at least the price of the selected item, the machine should dispense the item by printing "<item> Dispensed"; if the funds are insufficient, it should print "Insufficient funds"; and if the item is not available, print "Invalid item".

The input consists of two lines:

1. An integer representing the amount of money inserted (in cents).
