Describe a function (in C) that does the following Input : an integer. Output: if that integer is 4, the function returns 7. if that integer is 7, the function returns 4. constraints: the input is SURE to be either 4 or 7. no need to validate. you are not allowed to use any condition/flow commands (if, switch, while, for, trinary operator...) you are not allowed to use any external library or import anything (like math..) you are not allowed to use %(modulu), * (multiplication)
reverse bits of an integer that is a power of 2 , keeping complexity in mind.
Given an integer array, write a program that returns an array with elements = product of the integers in input array except the one in its position. Ex: Given input: [2, 3, 10, 4, 5], output: [600, 400, 120, 300, 240] What is the complexity of your program? When will your program not work? Below is what I presented (O(n)), but it did not qualify me for the next round.
