The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Solution - How to Loop in Solidity

The video tutorial guides viewers through creating a contract and setting up lists in a programming environment. It explains how to create a function that checks if a user-inputted number exists in a list, returning true or false. The tutorial also covers deploying the contract and testing the function. Additionally, it demonstrates how to create a function that counts even numbers in a list using a loop and modulo operation. The video concludes with a brief wrap-up and hints at future applications in smart contracts and DeFi.
