The questions are made to test the fundamentals of Java, javascript, Python, and as well as object-oriented programming concepts. This volume is covering:LoopStackFunctionsData StructureBoolean ExpressionPoccomu, in Latin, means uncommon. In this world of automation, artificial intelligence ("AI"), and changing consumer preferences - the workplace is changing rapidly too. Are we preparing our next generation to handle those uncommon situations? Will the new graduates be able to handle the uncertainty? Industry leaders are concerned because the present-education system is focused on standardized testing and rote learning. That's where POCCOMU comes in... Poccomu's methodology of logic-based testing of STEM will help in keeping pace with the uncommon challenges at the workplace. The idea of Poccomu is to push students to discover the power of their logical thinking using the fundamental concepts they have learned in STEM coursework when they encounter an uncommon problem. Poccomu is designed to push students to think out of the box way to simplify and to solve critical and uncommon problems. Encouraging a young and motivated brain to think out of the box will not only help him/her to outperform in standardized tests but also enhance their mental ability to solve the most inscrutable problem in their professional life.
