hello @achin1tya
initialse ur dp array with zero while computing answer for each test cases.

#4

HI , @aman212yadav , I used long dp[10000] = {0} in the initialisation . will it not work ?

#5

no,u should again initialise it inside while loop.

#6

yes , it worked . But why ? isnt {0} the same as initializing . Thx for the help

#7

that will intialise only once after each iteration ur dp array will contain some values (non zero) which are of no use for new testcase.therefore again intialising it with 0.
