Minimum Bit Modifications to Equalize User Roles Problem Description A web developer is responsible for managing user roles within an application, ensuring that each role grants the same access permissions. Currently, there may be disparities among user roles, leading to inconsistent access levels. To create a uniform experience for all users, the developer needs to standardize these roles. Given an integer array userRoles of length n . Your task is to ensure that all user roles have the same access level, creating a unified experience for all users of the application. You can modify the userRoles by performing the following operation any number of times (including zero): Select an index i ( 0 <= i < n ) and toggle any bit in the binary representation of userRoles[i] . Specifically, if a bit is currently set to 1, it will be flipped to 0, and if it is set to 0, it will be flipped to 1. Find the minimum number of bit modifications required to make all user roles in the array userR
