Given 4 integers a, b, y, and x, where x can only either 0 and 1 only. The ask is as follows:
If 'x' is 0, Assign value 'a' to variable 'y' Else (If 'x' is 1) Assign value 'b' to variable 'y'.
Note: – You are not allowed to use any conditional operator (including ternary operator) or any arithmetic operator ( +, -, *, /).
Input : a = 5 , b = 10, x = 1 Output : y = 10 Input : a = 5, b = 10 , x = 0 Output : y = 5
Asked in : Google Interview
An Idea is to simply store both 'a' and 'b' in an array at 0th and 1th index respectively. Then store value to 'y' by taking 'x' as index.
Below is implementation
Value assigned to 'y' is 5
