Yes That Solution on which i was asking my doubt took 15 ms But When i wrote a similar Solution it took 30 ms.
Can you explain me this line
int ans=ncr(q,(q+abs(val-vali))/2);
how is this giving us the favourable outcomes?
Iām still missing why we used nCr since the ā-ā position mattered we should have used nPr right ?
