Working with Android layouts, asynchronous communication, java libraries, REST API client architecture. One logical task: you have an array of 99 distinct integers, each one can have a value between 1 and 100 inclusively. But no duplicates in an array. Array is not sorted. Find out which value is missing in the array.
