1. Choose an index i (1 ≤ i ≤ n) from array a and index j (1 ≤ j ≤ n) from array b. 2. Swap a and b with the cost as min(a , b ). Your task is to minimize the total cost of all swaps needed to make the arrays identical. If it is ...
You want to randomly pick two numbers from the array and you need to ensure that the sum two numbers is always even. To achieve this, You may modify any element of array by either incrementing or decrementing it by 1, where the cost to change an element x is equal to x itself....
