THIS IS A SIMD METHOD QUESTION WITH C LANGUAGE. NOT LOOP PROGRAMMING OR BITWISE SOLUTION. SOLUTION SHOULD USE SIMD METHODS. IF YOU DONT KNOW SIMD ARCHITECTURE ON C DONT ANSWER. ANSWER MUST BE IN CONSTANT TIME O(1) and DOESNT INCLUDE FOR, WHILE etc LOOP. YOU MUST USE SIMD instricts

You are given sixty-four bit integer and wants to determine position of k'th set bit in contant time (means you cannot use any loop like while, for, foreach etc. you must solve with elegant way with one instructions and O(1) complexity) with SIMD instrict and describe your code clearly (if need you can use index scheme such as 0 base or 1 base)
