You can print these Questions in default mode to … At this point, the value 1 will be returned. Let’s write a c code which implement binary search algorithm using recursion. Many programming problems can be solved only by recursion, and some problems that can be solved by other techniques are better solved by recursion. For example the program below results in an infinite recursion. Java Program Practice Mcq Question and Answer.
