Say we are string from the right end and the array size is n. Now, pick the end element which will be the nth element, and pick up another element randomly from the range [0, n-1]. WebC++ solution with Fisher Yates algorithm. Use Fisher Yates algorithm to randomize. Keep an extra idx array to store the original index of each element, so that we can correctly reset each element to its original position. Also note that "srand (time (NULL))" must be placed in the constructor, not the shuffle () function. how to get sim id number sims 4
