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)
Find the second maximum element in an unsorted array of integers, using single for loop.
reverse bits of an integer that is a power of 2 , keeping complexity in mind.
How many unique paths are there from B-L point to the T-R point of a chess table? What would be your approach to calculate this?
Reverse the words in a sentence. For example, "Have a nice day" becomes "day nice a Have"
string compression: aaabbbbcc ->a3b4c2
You have two linked lists that merge at some node. The lists could be billions of nodes long. Find the node where the lists merge in the most optimal time while using a low amount of memory.
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.
