#1

I’m not clear on how I’ll use dynamic programming.

@ranaabhinav50 hi bhai,in this question ,there are some pairs given to you. Pairs may/may not contain same element.(Don’t get confused because of “shoes”)
You have to select one element from each pair.
Sum of all elements you pick should be odd.
For given test case,these are possible:
1+3 (even,invalid)
1+4 (odd,valid)
2+3 (odd,valid)
2+4 (even,invalid)
Hence answer is 2.
