valarray pow() function in C++

The pow() function is defined in valarray header file. This function returns a valarray containing the results of the power operation on all the elements, in the same order. Syntax:

pow(varr, n);

Parameter:

• varr: This represents the valarray object.
• n: It represents a exponent value.

Returns: This function returns a valarray containing the results of the power operation on all the elements. Below programs illustrate the above function: Example 1:- 

The new valarray with manipulated values is : 
-1 8 27 64 -125

Time complexity: O(N)

Space complexity: O(1)

Example 2:- 

The new valarray with manipulated values is : 
1 36 9 16 25

Time complexity: O(N)

Space complexity: O(1)
