HackerEarth Picu Bank problem solution YASH PAL, 31 July 202415 February 2026 In this HackerEarth Picu Bank problem solution, You have D dollars with you. You want to put it into a Bank, namely Picu Bank. This bank has a peculiar behavior for interest. Regardless of the Bank deposit amount, every month it adds A dollars to your bank account and this continues till M months. Exaxtly on M + 1 months, it adds B dollars (B < A) to your bank account. This scanario repeats again in same manner.( i.e on the (M + 2)th month A dollars are added, and so on.. ). Your task is to find out how many months does it take for the dollar amount to reach at least X, in the bank account.
