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.
1) Move all the element less than a given number to right side and greater than given number to left side. Number can or can not be part of Array 2) There are three unsorted(confirmed twice from him) array of size x, y, z. I had to form a third array whose size will be (n + m + l) and put all the elements in sorted order. 3) Check if given Parentheses are balanced or not.
