+/**
+* Curries a function, allowing it to be called with a single argument at a time and returning a new function that takes the next argument.
+* This process continues until all arguments have been provided, at which point the original function is called with all accumulated arguments.
+*
+* @param func - The function to curry.
+* @returns A curried function that can be called with a single argument at a time.
+*
+* @example
+* function sum(a: number, b: number, c: number) {
+*   return a + b + c;
+* }
+*
+* const curriedSum = curry(sum);
+*
+* // The parameter `a` should be given the value `10`.
+* const add10 = curriedSum(10);
+*
+* // The parameter `b` should be given the value `15`.
+* const add25 = add10(15);
+*
+* // The parameter `c` should be given the value `5`. The function 'sum' has received all its arguments and will now return a value.
+* const result = add25(5);
