Get exponential value of a number using Math.exp in Java | To get the exponential value of a number in Java, we use the java.lang.Math.exp() method.

If the argument is positive infinity, then the result is positive infini... | [

Find closest number in array in C++ | Suppose we have an array A with n elements. And elements are sorted. We have to find the closest value to the given integer. The array may contain duplicate values and negative numbers. So if the array is like [2, 5, 6, 7, 8, 8, 9] and the target number is 4, then closest element is 5.
