Consider an array X that contains n positive integers. A subarray of X is defined to be a sequence of array locations with consecutive indices.

The C code snippet given below has been written to compute the length of the longest subarray of X that contains at most two distinct integers. The code has two missing expressions labelled (P) and (Q).

int first=0, second=0, len1=0, len2=0, maxlen=0; for (int i=0; i < n; i++) { if (X[i] == first) { len2++; len1++; } else if (X[i] == second) { len2++; len1 = (P); second = first; } else { len2 = (Q); len1 = 1; second = first; } if (len2 > maxlen) { maxlen = len2; } first = X[i]; }

Which one of the following options gives the CORRECT missing expressions?

(__ Hint:__ At the end of the i-th iteration, the value of len1 is the length of the longest subarray ending with X[i] that contains all equal values, and len2 is the length of the longest subarray ending with X[i] that contains at most two distinct values.)
