hi @abhinavai21_5c95a2a2e1fb9fe8 your approach is wrong
refer u dont need to calculate the sum by shifting again and again, anyway u will be adding the array sum of that array only even if u shift and add as u r adding all the elements so dont shift just keep updating the sum of array

see here for implementation https://ide.codingblocks.com/s/657171 and do a dry run
