text: Longest Increasing Odd Even Subsequence | function to find the longest increasing odd even subsequence ; lioes [ i ] stores longest increasing odd even subsequence ending at arr [ i ] ; to store the length of longest increasing odd even subsequence ; Initialize LIOES values for all indexes ; Compute optimized LIOES values in bottom up manner ; Pick maximum of all LIOES values ; required maximum length ; Driver Code
