To check if a number is a power of 2, we can use bitwise operations.
A power of 2 has only one bit set to 1, so we can use the bitwise AND operator to check if the number is a power of 2.
If n is a power of 2, then n & (n-1) will be 0.
For example, 8 (1000 in binary) is a power of 2, and 8 & 7 (0111 in binary) is 0.
Sort a stack without using another data structure
Use recursion to pop the top element and insert it at the bottom of the remaining stack
Repeat until the stack is sorted in ascending order
Time complexity: O(n^2), space complexity: O(n) due to recursion

Loop through the array and check if each element is greater than the previous one
