( 11091 ) G Hits Different PROGRAMMING data structures dp implementation math 1600

B"In a carnival game, there is a huge pyramid of cans with 2023 rows, numbered in a regular pattern as shown. If can 9^2 is hit initially, then all cans colored red in the picture above would fall. You throw a ball at the pyramid, and it hits a single can with number n^2 . This causes all cans that are stacked on top of this can to fall (that is, can n^2 falls, then the cans directly above n^2 fall, then the cans directly above those cans, and so on). For example, the picture above shows the cans that would fall if can 9^2 is hit. What is the sum of the numbers on all cans that fall? Recall that n^2 = n x n . The first line contains an integer t ( 1 <= q t <= q 1000 ) -- the number of test cases. The only line of each test case contains a single integer n ( 1 <= q n <= q 10^6 ) -- it means that the can you hit has label n^2 . For each test case, output a single integer -- the sum of the numbers on all cans that fall. Please note, that the answer for some test cases won't fit into 32-bit integer type, so you should use at least 64-bit integer type in your programming language (like long long for C++). For all valid inputs, the answer will always fit into 64-bit integer type. The first test case is pictured in the statement. The sum of the numbers that fall is 1^2 + 2^2 + 3^2 + 5^2 + 6^2 + 9^2 = 1 + 4 + 9 + 25 + 36 + 81 = 156. In the second test case, only the can labeled 1^2 falls, so the answer is 1^2=1 . In the third test case, the cans labeled 1^2 and 2^2 fall, so the answer is 1^2+2^2=1+4=5 . In the fourth test case, the cans labeled 1^2 and 3^2 fall, so the answer is 1^2+3^2=1+9=10 . In the fifth test case, the cans labeled 1^2 , 2^2 , and 4^2 fall, so the answer is 1^2+2^2+4^2=1+4+16=21 . "...
