QUEUE using STacks:Vinisha Ma'am

Implement a queue using two stacks
REduce the time as much as possibble

time complexity for queue operation will be O(1)
and deque operation will be...
pop all and push in second stack + pop topmost + pop all and push again bak in first array
O(n)+O(1)+O(n-1)=O(n)

can it be bettered???

no it cant be better......ya to tujhe pop operation O(n) rakhna padega ya phir push operation O(n) rakhna padega...
dono mein se ek O(n) chalega and dusra O(1)
