Ans. 
Calculate the total amount of rainwater that can be trapped between given elevations in an array.
• Iterate through the array and calculate the maximum height on the left and right of each bar.

• Calculate the amount of water that can be trapped at each bar by taking the minimum of the maximum heights on the left and right.

• Sum up the trapped water at each bar to get the total trapped water for the entire array.

Ans. 
Identify the element that appears an odd number of times in an array of integers where all other elements appear an even number of times.
• Iterate through the array and use XOR operation to find the element that appears an odd number of times.

• XOR of a number with itself is 0, so XOR of all elements will give the odd occurring element.

• Return the result after XORing all elements in the array.
